We propose to develop tunable, high-power handling, low-loss phase-to-amplitude conversion photonic-integrated circuit (PIC) based device on heterogeneous SiN platform. The use of SiN for waveguide is the key to meet the stringent requirements, while additional heterogeneously integrated components are the key to enable tuning and locking of the phase-to-amplitude device. Nexus Photonics, realizi ...

Knowledge graphs are information networks with a specific topology. The topology is simple enough that we do not need graph grammars to specify the subgraphs that belong to a mission graph. Knowledge graphs can be modeled as terms of an algebraic data type in a type system called Flutes. Flutes was created by Datanova Scientific to rigorously analyze formal approaches to semantic integration. This ...

Freedom Photonics is proposing to develop a novel modulator concept. The overall objective of this program is to develop a novel compound-semiconductor electro-optic modulator that simultaneously exhibits 100-GHz operation, optical/microwave velocity matc

In this program, we propose to adapt a new, high-performance integration platform for RF photonics to operation at 1um, and to realize integrated optical transmitters that meet the requirements of the program.

Vescent Photonics, LLC, (Vescent) and the Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL) propose to develop a low-noise, field-deployable vector magnetometer based on the dispersive cavity readout (DCR) of nitrogen vacancy (NV) diamond.  Solid-state quantum systems based on NV-diamond centers have many intrinsic properties that make them well-suited as stable, sensitive platfor ...
