More than half of proposals are rejected for being “non-responsive.” This is because many scientists make the mistake of believing that a grant is a “grade”—that if their research is good enough, then a reviewer will give them money based solely on the merit of their research. The quality of a proposal is irrelevant, though, if the proposed research project does not align with the goals and purpose of the funding agency. A compelling grant proposal must be responsive to the topic, engaging to read, and easy to understand. This webinar presents five critical things a researcher can do to craft proposals that rise to the top of a reviewer’s stack.

Working in industry is different than academic research in some important ways. Chances are, your advisor has only worked in academia and is not able to help you prepare for an industry career. I’ll give you some ideas for preparing for that career while you are still in university, so that you sound much more industry-ready in that first interview.
This webinar will teach the participants the following:
1. How working in industry is different than academic research
2. Tools that industry uses but you probably haven’t learned in university
3. How to make your dissertation project sound more relevant to an industry hiring manager

Optical communications has enjoyed tremendous impact over the past 50 years. Relatively soon after the concrete proposal of optical fiber communications was reported and the low-loss fiber was demonstrated, fiber-based communications dramatically impacted the way society transfers information. However, there are other key areas beyond fiber-based communications that were also envisioned ~50 years ago but are only recently emerging. Such emergence is due to enhanced capacity needs and critical innovations, including advances in photonic integrated circuits (PICs). This webinar will highlight various examples of the innovations and emerging applications of optical communications, including:
1. Free-space optical communications: As opposed to RF, optical links have high directionality and large bandwidth. There is great excitement in the recent emergence of deployed free-space optical links, be they through air or outer-space. Moreover, due to the extremely high losses of RF, even underwater links in the blue-green are gaining significant interest. Also to be discussed is capacity enhancement using multiplexing of multiple orthogonal beams.
2. Non-conventional wavelengths: Fiber systems are overwhelmingly in the near-IR, whereas free-space links can take advantage of a much wider frequency range, from THz to visible. Such systems may utilize: (a) native high-speed components, and/or (b) wavelength-band conversion of near-IR channels to other frequencies.
3. Optical signal processing (OSP): OSP has long held the promise of high-speed operation and the avoidance of inefficient optical-electrical-optical conversion. Although OSP deployment has been limited, advances in PICs, power efficiency and multi-wavelength operation may soon enable the emergence of OSP for high-performance functions.

Scientists and engineers often struggle to plan a private sector career. Most of our
professors have no experience designing an industry career path and can’t help us. I
recall my own advisor telling me “If you go into industry, you are on your own!”
But it’s not as hard as it seems to design a career path that is exciting, rewarding, and
most of all, fits your own personal strengths and interests. In this webinar Dr. Giltner will teach you the process. Dr. Giltner has used his own career and have taught to many others.

The new internet based on IPv6 The IPv6 Deployment worldwide is becoming a reality now with some countries achieving more than 60% user penetration with France (70%), Belgium (63%), USA (50%) and India (60%) at the top ranking (http://labs.apnic.net/dists/v6dcc.html) and reaching double digits v6 coverage on Google IPv6 stats. May Autonomous Networks (ASN) reach more than 90% with v6 preferred or v6 capable: (http://labs.apnic.net/ipv6-measurement/Economies/US/). Over 2.5 Billion users are accessing Internet over IPv6 and probably not even knowing it. (http://www.google.com/intl/en/ipv6/statistics.html). If this trend continues, we should achieve 90% by 2025 which would be the inflection point when the full roll-out of IPv6 becomes a strategic plumbing decision of the networks to move to IPv6-Only and start divorcing IPv4 from the Internet. The US Government has already set some dates to move to IPv6-Only by 2025.
New topics are more on the lime light such as Cloud Computing, Internet of Things, 5G/6G, … However, these fields are taking IP networking for granted designing them on IPv4/NAT building non-scalable and non-end to end solutions. The IPv6 Forum is driving new initiatives to garner support and create awareness in these areas: www.ipv6forum.org.

The evolution of commercial wireless networks to 5G and beyond will continue to increase the demands for wireless spectrum. Traditionally, commercial wireless service providers have utilized spectrum that is exclusively licensed to them. Moving forward, these networks will increasingly operate in spectrum that is shared including utilizing unlicensed spectrum and the tiered sharing approach recently adopted for the Citizens Broadband Radio Service (CBRS) adopted for sharing the 3.5 GHZ band with incumbent users. The success of these approaches is in turn tightly coupled to the economic impact they have on the competition between wireless service providers. In this talk we will discuss a framework for gaining insight into these impacts based on game theoretic models for competition with congestible resources. We will utilize this framework to illustrate potential impacts of different emerging sharing scenarios.

The field of quantum photonics promises to revolutionize the way in which we process information, thanks to the peculiar and counterintuitive properties of quantum states of light. In this regard, the use of photonic integrated circuits (PICs) will enable the miniaturization of the experimental setup needed for the generation, manipulation, and detection of single photons, beneficial for achieving a stable and scalable operation. During this talk, the role of femtosecond laser waveguide writing in the field of quantum photonics will be discussed. This microfabrication platform, based on the nonlinear interaction between an ultrafast laser and a transparent substrate, provides unique advantages, such as the possibility of inscribing complex three-dimensional waveguiding structures with low losses and a polarization insensitive behavior. After a general introduction, some selected applications of fs laser written PICs will be reported, mainly in the field of quantum information processing and quantum artificial intelligence with photons.

Many areas in Photonics demand the design and construction of complex optical systems that require overcoming challenges in control, efficiency, and miniaturization, which are not possible to achieve with the usual diffractive and refractive elements. Recently, a promising type of optics has emerged that exploits the geometric phase
(GP) shift also known as Pancharatnam–Berry phase to modify wavefronts or shaping beams by introducing spatially varying anisotropy. GP promises a new generation of electro-optical elements with arbitrary phase profiles that potentially can overcome those challenges and be incorporated into a wide variety of modern optical systems to have improvements in a wide range of applications.

With 5G ramping up, enabling groundbreaking services, and opening up business opportunities, it’s a great time to talk about optical fiber networks and recall that they are at the foundation of mobile connectivity.
While we mostly use mobile devices to connect to the network, all this data from phone and video calls, streaming, and social media is aggregated at a nearby site and converted to/from optical signals carried over optical fiber.
Optical networks ensure efficient transmission of large data volumes with low latency – across a city, a state, a continent, or even an ocean. And as requirements for bandwidth and differentiated services go up, optical networks continue to evolve.
In this webinar, Teresa Monteiro will discuss current challenges in optical networking and the diversity of skills and profiles required to advance this domain. She will also share aspects of her own career, which started in high-energy physics and evolved to optical system engineering, product management, and solution marketing and communications. There have been times in Teresa’s career when she settled and other times when she laced up the hiking boots to explore. What will your journey be like?
