Recirculating photonic filter: a wavelength-selective time delay for phased-array antennas and wavelength code-division multiple access

S Yegnanarayanan et al. Opt Lett. .

Abstract

A novel wavelength-selective photonic time-delay filter is proposed and demonstrated. The device consists of an optical phased-array waveguide grating in a recirculating feedback configuration. It can function as a true-time-delay generator for squint-free beam steering in optically controlled phased-array antennas and as an encoding-decoding filter for wavelength code-division multiple access.
