Abstract

In this paper, a MicroPhotonic-based high-Q tunable RF filter architecture is proposed. The architecture uses a Vertical Cavity Surface Emitting Laser (VCSEL) array, a 2D ultra-wideband photo-receiver array and a multi-cavity optical substrate to generate a large number of optical true-time delays thus achieving arbitrary, high-resolution RF filter transfer characteristics. By tuning the responses of the different optical cavities, adaptive high-Q RF filter characteristics can be realized over a wide RF frequency range. Proof-of-concept experimental results demonstrate the adaptability of the MicroPhotonic-based RF filter.
