Paper Abstract

Photonic microwave true-time delay eliminates the beam squint problem in broadband phased-array antenna. However the large insertion losses associated with the optical switching network that selects the appropriate delay line is a serious limitation. We have previously demonstrated a unique photonic filter that uses the optical carrier wavelength in the 1550 nm wavelength band to select the desired time delay. In this paper, dual band (1550/1300 nm) operation of this Recirculating Photonic Filter True-Time- Delay is demonstrated. This dual-band operation offers flexibility in system design, enhanced antenna functionality and is expected to lead to lower device and system cost.
