Abstract:
1. An optical device comprising: an input port (Pi); a splitter (SP) splitting an input light from the input port (Pi) into a plurality of coherent copies of the input light simultaneously, the input light being a coherent light; a plurality of waveguides connected with the splitter (SP), each of the plurality of coherent copies of the input light passing on each of the waveguides; a plurality of phase shifters (PS), inserted along with each of the waveguides, wherein each of phase shifters (PS) is capable of shifting the light split by the splitter (SP); a multi-port encoder/decoder (RID), the multi-port encoder/decoder (E/D) being connected with all of the waveguides, all of the light from the phase shifters (PS) being input into the multi-port encoder/decoder (E/D), wherein the multi-port encoder/decoder (E/D) encodes all of the input light from the phase shifters simultaneously so that it generates spectral encoded codes simultaneously; and a plurality of output ports (Po), the output ports (Po) being connected with the multi-port encoder/decoder (E/D), the output ports (Po) outputting the spectral encoded codes generated by the multi-port encoder/decoder (E/D); wherein the multi-port encoder/decoder (E/D) comprising:
