Abstract

A compact and affordable photonic true-time-delay lines for phased-array antenna applications using multiplexed substrate guided wave propagation is reported. Optical signals are fed into the device through surface normal to substrate holographic grating couplers recorded on DuPont HRF-600 photopolymer films. Various optical delays are obtained through optical fanouts at consecutive substrate bouncing positions through holographic output couplers. Design issues on the TTD architecture and the making of slanted holographic grating couplers with controllable diffraction efficiencies are discussed. The non-uniform intensity fanout problem, which is common for substrate guided approach due to cascaded propagations, is addressed and an 1D 8 delay lines with fanout intensity fluctuation within 10% is demonstrated. As a test for ultra-wideband operation, 25 GHz microwave signals, generated through optical heterodyne technique, are made to transmit through the device and subsequently detected with a signal-to-noise ratio of 20 dB.
