A 7 bit photonic true time delay system based on an 8\times8 MOEMS optical switc

We demonstrate a 7-bit photonic true-time-delay (TTD) system which uses an 8\times8 micro-optical-electro-mechanical system (MOEMS) optical switch for phased array antennas (PAAs) beamforming applications. The switch controls the optical signal to pass by the fiber delay lines (FDLs) of diff
