Military researchers eye next generation of chip-scale photonics to convert light into microwave energy

Sept. 18, 2024
This workshop will explore how to identify opportunities in moving low-noise photonic oscillators into system-level RF applications.

ARLINGTON, Va. – U.S. military researchers will brief industry next month on an upcoming project to develop the next generation of chip-scale photonics that produce microwaves with a combination of low-phase noise, broad frequency agility, compact form factor, and mass manufacturability.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., will conduct industry briefings on this photonic microwave oscillators project from 9 a.m. to 5 p.m. on 10 Oct. 2024 at the Virginia Tech Research Center, 900 North Glebe Road, in Arlington Va.

Two years ago DARPA launched the Generating RF with Photonic Oscillators for Low Noise (GRYPHON) program to investigate whether chip-scale photonics can produce microwaves with an unprecedented combination of low phase noise, broad frequency agility, compact form factor, and mass manufacturability.

GRYPHON performers are hQphotonics Inc. in Pasadena, Calif.; the California Institute of Technology (Caltech) in Pasadena, Calif.; and the University of Virginia in Charlottesville, Va.

Since then, oscillator demonstrations have achieved orders of magnitude improvements in performance compared to any microwave energy sources of comparable size.

This workshop will explore the next steps to advance photonic oscillators into RF systems of defense and commercial capability. DARPA seeks to foster discussions between technology developers, systems integrators, and manufacturers to identify challenges and opportunities in switching low- noise photonic oscillators into system-level RF applications.

Workshop goals are to showcase advances in low-noise photonic oscillator technology achieved by the GRYPHON program; discuss outstanding technical challenges to realize fieldable RF capabilities leveraging photonic oscillators; identify technology transfer partnerships; and stimulate new concepts in low-noise oscillators.

The workshop will include overview presentations by government, industry, and academic personnel -- including the GRYPHON performers and DARPA.

Companies interested should register for the industry briefings no later than 1 Oct. 2024 online at https://web.cvent.com/event/0cc76133-83fc-4bd6-8c83-fb85e2c13952/regProcessStep1. The event website is https://web.cvent.com/event/0cc76133-83fc-4bd6-8c83-fb85e2c13952/summary.
