From Semiconductor Nanolasers to Photonic Integrated Circuits

Hosted By: Laser Systems Technical Group

07 March 2017 13:00 - 14:00

Eastern Time (US & Canada) (UTC -05:00)

Metal-clad semiconductor nanolasers have recently become excellent candidates for light sources in densely-packed chip-scale photonic circuits due to their electromagnetic isolation from surrounding components, small footprint and enhanced emitter-field interactions. In webinar hosted by the OSA Laser Systems Technical Group, Dr. Qing Gu from the University of Texas at Dallas will discuss the design, fabrication, and characterization of semiconductor metal-clad nanolasers.

During this hour-long webinar, Dr. Gu will also outline an integrated treatment of multiple design aspects beyond pure electromagnetic consideration. To better understand emitter-field interactions in nanoscale devices, Dr. Gu will describe a formal treatment of the Purcell effect – the modification of the spontaneous emission rate by a sub-wavelength cavity. Finally, Dr. Gu will discuss during the webinar other nanoscale laser configurations and emerging light emitting materials on the silicon platform, as well as perspective for integrated photonic circuits.

What You Will Learn:

Attendees will learn the current status of semiconductor nanoscale lasers, in particular the metal-clad type with III-V semiconductors.
Attendees will learn approaches to insert nanolasers into photonic integrated circuits.

Government and Industry Researchers

Presenter

Dr. Qing Gu

Qing Gu is an Assistant Professor of Electrical Engineering at UT Dallas since January 2016. She received the Bachelor of Applied Science degree from the University of British Columbia, Canada in 2008, and the Ph.D. degree from the University of California, San Diego (UCSD) in 2014, both in Electrical Engineering. Her research interests include the design, fabrication and characterization of nano- and micro- scale photonic devices (such as lasers, waveguides and sensors), novel light-emitting materials and optical cavity configuration, quantum behavior analysis in nanostructures, and integrated photonic circuits. She is the author of book “Semiconductor Nanolasers” by Cambridge University Press (to be published in February 2017).
