An approach for realizing low-power, high-port-count optical switching systems, such as OXCs, WXCs, and ROADMs is presented. Optical switching systems in accordance with the present disclosure include arrangements of frequency-filter blocks, each of which includes a cascaded arrangement of tunable couplers and tunable Mach-Zehnder Interferometers (MZIs) that provides a substantially flat-top broadband transfer function for the frequency-filter block. The tunability for these devices is achieved by operatively coupling a low-power-dissipation phase controller, such as a stress-optic phase controller or liquid-crystal-based phase controller with one arm of the device, thereby enabling control over the coupling coefficient of the device.

Aspects of the present disclosure describe planar lightwave circuit systems, methods and structures including a resonant mirror assembly having cascaded resonators that provide or otherwise facilitate the control of the transmissivity/reflectivity of a planar lightwave circuit (PLC)&#x2014;or portion thereof&#x2014;over a range of 0% to substantially 100%.

Planar lightwave circuits (PLCs) exhibiting controllable transmissivity / reflectivity

A phased-array antenna that includes a photonic beamformer is disclosed. In some embodiments, a front stage of electrical-domain processing applies a 16-to-1 signal-combination ratio, a single stage of photonic beamforming applies a 4-to-1 signal-combination ratio, and a passive, electrical-domain, signal combiner applies a 32-to-1 signal-combination ratio.
