Evening and Keynote Session

Brian Sullivan

Iridian Spectral Technologies Ltd., Canada

KEYNOTE: New Trends and Developments in Precision Filters and Their Applications

This talk will explore the applications of precision optical filters in the fields of telecommunications (free space and fiber), life sciences, space (earth observation and satellite inter-links), lidar, quantum computing/communications and astronomy and discuss new trends and developments of optical filters in these fields. As well, some aspects of optical filters (such as phase control and group delay) that are critical to ensuring that the filter operates as expected in its intended application will be briefly discussed. Theoretical and measured results of different optical filters will also be shown.

About the Speaker

Brian Sullivan graduated with a Ph.D. in Optical Physics from the University of British Columbia in 1987. Brian then joined the Thin Films Group at National Research Council of Canada first as a post-doc and then as a Research Scientist. The Thin Films Group, lead by George Dobrowolski, was involved in practical applications of optical coatings which resulted in interactions with many private companies and lead to the development of methods to automate the deposition of optical filters. Based on technology developed at the NRCC, Brian founded Iridian Spectral Technologies Ltd. in 1988 along with Peter Dawson. Iridian first fabricated optical filters for telecommunication applications and then for other fields including spectroscopic filters (life sciences and instrumentation), 3D cinema, space and astronomy, covering the spectral range from the UV (325 nm) to the LWIR (16 um). Brian is CTO of Iridian and remains actively involved in the development of optical filters for new applications.

Michel Lequime

Institut Fresnel, France

KEYNOTE: Fourier transform formalism for the description of electromagnetic phenomena in modern multilayers applications

Optical thin films, as 2D spatially invariant structures, are ideally suited to implement decomposition of the electromagnetic field on a plane-wave basis. We show how such a basis choice results spontaneously from solving of Maxwell’s equations using two consecutive Fourier transforms, the first in the time domain and the second in the spatial invariance plane of the layers.This approach logically leads to the introduction of the central concept of complex admittance, and we show how this allows to describe within a unified approach various complex phenomena, such as giant field enhancement in dielectric stacks, light scattering from thin-film optical filters, and optical properties of planar multilayer microcavities.

About the Speaker

Michel Lequime received his Master's in Engineering from the Institut d'Optique Graduate School in 1974 and his PhD degree from Paris-Sud University in 1977. His doctoral research was devoted to the study of third-order non-linear optical processes at the picosecond scale. In 1979, he joined BERTIN, a French Contract Research Organization, to participate in the creation of an optical group at the company. Its activities dealt mainly with Space Optics (Multicolour Camera for the observation of Halley's Comet - ESA Giotto probe, Optical Beacon for the ESA Semi-Conductor Inter Satellite Link Experiment - SILEX) and Optical Fiber Sensors (inline color measurement of refined fuels, pressure and temperature measurements for down-hole applications). In 2000, he joined the Ecole Centrale Marseille as Professor of Optics and Project Management and the Institut Fresnel as Senior Scientist. From 2002 to 2014, he was in charge of the Optical Thin Films Group at the Institut Fresnel. He is currently Emeritus Professor at Centrale Marseille and continues to pursue his research activities at the Institut Fresnel on the development of instrumentation for the comprehensive characterization of the optical properties of multilayers components. Michel Lequime has served as Secretary to the French Optical Society from 2009 to 2012 and is the author of more than 300 publications and communications in the field of Optics.

Technology Showcase: Single-Crystal Interference Coatings for High-Performance Infrared Optics

Wednesday, 22 June 17:35 – 17:55

Speaker: Dr. Garrett D. Cole, Technology Manager, Thorlabs Crystalline Solutions

Substrate-transferred crystalline coatings are a groundbreaking concept in optical interference coatings. Production of these “semiconductor supermirrors” entails a unique manufacturing process utilizing separate crystal growth, microfabrication, and direct bonding, which ultimately yields single-crystal coatings on arbitrary—including curved—optical surfaces. These coatings were first detailed in 2013 with the key advantage being the ability to achieve ultralow levels of optical and elastic losses. Following nearly a decade of continuous refinement, we have reduced the scatter + absorption losses to < 3 parts per million (ppm) for wavelengths spanning 1000 to 1560 nm, enabling a cavity finesse exceeding 600,000 (mirror reflectance > 99.9995%). In this spectral range, crystalline coatings are fully competitive with ion-beam sputtered films, while simultaneously yielding a significant reduction in Brownian thermal noise, a fundamental limitation in the stability of laser-based precision measurement systems including gravitational wave detectors and cavity-stabilized lasers for optical atomic clocks. Additional advantages of these novel monocrystalline coatings include record-low-levels of mid-infrared optical losses, with excess losses below 10 ppm measured at ~4600 nm, as well as an exceptionally high thermal conductivity for an ultralow-loss multilayer. Looking ahead, we see a bright future for crystalline coatings in applications requiring the ultimate levels of optomechanical and thermal performance.

The Optical Interference Coatings conference sponsors three contests in the areas of design, manufacturing, and measurement.  Following are the descriptions and submission information for each of the three contests.

Design Contest

An exciting component of the Optical Interference Coating (OIC) topical meeting is the design contest. The contest traditionally presents two challenging design problems to the optical thin-film community. The participating designers can use whatever design software or design techniques they prefer in order to meet the specifications called out in the problem statement. Web-based evaluation software will be provided to participants to check their results. An examination of all of the design techniques and submitted solutions provides valuable insights and helps to advance the knowledge base of the optical thin-film community. The design contest results will be presented at the OIC conference. The designs and associated designer list will be disclosed.

Manufacturing Contest 

The purpose of the Manufacturing Contest is to demonstrate the state-of-the-art in optical thin film manufacturing by challenging participants to manufacture a demanding optical filter. The contest has attracted many participants in the past from industries, research organizations and universities since it was first held in 2001. Participants can use any optical design, deposition technique and measurement equipment to manufacture the filter on supplied blank substrates according to the specification in the contest description. Three independent laboratories will evaluate the submitted samples only for the required performance rating and samples will be returned to participants at the OIC conference. The manufacturing contest results will be presented at the OIC conference. As in the previous contests, only the participant with the top-rated sample will be named. All other participants will be acknowledged, but not associated with a specific sample.

Measurement Contest 

The ability to measure accurately the performance of optical coatings is essential to the successful design and manufacturing of optical coatings, especially for demanding applications. The OIC Measurement Contest challenges participants to use whatever techniques or equipment available to them, to measure the performance of supplied coating samples according to the specification in the contest description. The samples supplied by the contest are fabricated by durable deposition process and have passed a durability test before being distributed to participants. The submitted measurement results by participants will be presented at the OIC conference in an anonymous manner. All participants will be acknowledged.
