In this Project, OEwaves Inc. and Georgia Tech propose to research and develop an RF photonic receiver front-end enabling microwave signal processing at a heterogeneously integrated photonic platform. In particular, we propose to develop a new technology for photonic microwave filters based on the new advances in silicon (Si)-based integrated photonics. In this endeavor, we will exploit the expertise of the team members who have made extensive contributions to Si and silicon nitride (SiN) int…

One feature pertains to an apparatus that includes apparatus that includes an evanescent field coupler having a first surface that evanescently couples light between the evanescent field coupler and an open dielectric resonator. The apparatus also includes a thin film coating covering at least a portion of the first surface of the evanescent field coupler. The thin film coating is specifically designed so that the thin film coating reflects light of a first wavelength.

The disclosure relates in some aspects to an open dielectric resonator with nanoparticles secured on its outer surface, where the nanoparticles are located, sized and/or shaped to increase an amount of backscattered light in the resonator to provide substantially lossless, coherent backscattering of light. In some examples, fine particles are used instead of nanoparticles. Other features relate to a laser system having a plasmon-activated cavity optically coupled to a laser where the plasmon-…

The disclosure relates in some aspects to a two-point locking system for stabilizing a frequency comb oscillator using at least two optical transitions of the same atomic/molecular sample. In an example, an optical reference sample is characterized by two or more optical transitions. A coherent light source provides polychromatic coherent light (such as an optical frequency comb). The beams of light, occupying the same spatial mode volume or separated in space, and having frequencies in the v…

The disclosure relates in some aspects to Light Detection and Ranging (LIDAR) for underwater applications. An exemplary LIDAR system described herein uses a green and/or blue semiconductor laser, which is self-injection locked using a high-quality factor micro-resonator, such as a whispering gallery mode (WGM) resonator. The self-injection locking results in a single mode operation of the laser and reduction of its linewidth. The self-injection allows transferring frequency modulation from th…
