Nonvolatile photonic field-programmable coupler array
. The demonstrated devices achieve an ultrashort active length (<10 μm, more than 15 times smaller than the current state of the art of competing technologies) and zero static power, in combination with high-extinction switching (>20 dB), broadband operation (>15 nm), and low insertion loss (<2 dB). This work forms the basis for nonvolatile field-programmable coupler arrays (nv-FPCAs) and zero-static power reconfigurable optical interconnects.
