Programmable Photonic Circuit for Optical Logic Operations and 2-Bit Decoding
Noel Francisco Prado Bucaro, Yushan Hu, Satoshi Sunada +1
We present a programmable silicon photonic circuit composed of cascaded multiport directional couplers interleaved with thermo-optic phase shifters. The device forms a reconfigurab…
