Abstract
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) integrated photonic structures (Georgia Tech) and the design and development of analog photonic systems (OEwaves Inc.).OEwaves will apply a rapid development process using existing, proven, photonic elements to develop a wideband chip-scale tuner, with IF filtering capabilities. The extremely fast and compact tuning architecture provides a viable alternative to currently available high-cost channelized architectures.nbsp; The development approach is a front-end architecture based on the application of novel integrated optical filters characterized by ultra-high quality-factors (ldquo;Qsrdquo;) coupled with a capable back-end. nbsp;Photonic circuit elements based on the filters allow highly selective processing of the narrow-band, weak, and scattered RF and microwave signals.nbsp; The integrated optical resonators enable a versatile RF photonic tuner architecture by optimizing RF parameters such as selectivity, bandwidth coverage, tuning extent and speed relative to size, weight, and energy efficiency. The goal of the current project is to create an integrated filter prototype system at the end of Phase II.nbsp;nbsp;
