A heterogeneously integrated silicon photonic/lithium niobate platform for RF photonics

AVFOP 2019 - Avionics and Vehicle Fiber-Optics and Photonics Conference

Boynton, Nicholas; Cai, Hong; Gehl, Michael; Arterburn, Shawn C.; Dallo, Christina M.; Pomerene, Andrew; Starbuck, Andrew L.; Hood, Dana; Trotter, Douglas C.; Friedmann, Thomas A.; Derose, Christopher T.; Lentine, Anthony L.

We present a 30 GHz heterogeneously integrated silicon photonic/lithium niobate Mach-Zehnder modulator simultaneously utilizing the strong Pockels effect in LiNbO3 while also taking advantage of the ability for photonic/electronic integration and mass production associated with silicon photonics. Aside from the final step of bonding the LiNbO3, this modulator can be entirely fabricated using CMOS facilities.

Photonic integrated circuits for simultaneous channelization and downconversion

AVFOP 2019 - Avionics and Vehicle Fiber-Optics and Photonics Conference

Yang, Benjamin B.; Lovelace, Brandon; Wier, Brian R.; Campbell, Jacob; Bolding, Mark; Chan, Cheong W.; Vinson, J.G.; Muthuchamy, Tarun; Bhattacharjea, Rajib; Harris, T.R.; Davis, Kyle; Stark, Andrew; Ward, Christopher; Bottenfield, Christian; Ralph, Stephen E.; Gehl, Michael; Kodigala, Ashok; Lentine, Anthony L.

A compact radio frequency (RF) photonic receiver consisting of several photonic integrated circuits (PIC) that performs channelization and simultaneously downconverts the signal is described. A technique is also presented to adjust the phase shifters of the arrayed waveguide grating channelizer without direct phase measurements.

Organizational Resilience; Business Continuity

De La Rosa Galey, Diana M.

In FY 19, the Sandia National Laboratories' "Laboratory Resilience and Continuity Management" Organization established the groundwork to create a business continuity program. The organization is leveraging best practices from established industry and ISO standards and Federal Emergency Management Agency (FEMA) continuity guidance.
