Abstract
Disclosed herein is a recirculating programmable photonic circuit including a programmable optical coupler including two first programmable waveguides and configured to adjust optical coupling efficiency of an optical signal based on a vertical movement of one of the two first programmable waveguides, a phase shifter including a second programmable waveguide and configured to change a phase of the optical signal based on a horizontal movement of the second programmable waveguide with respect to the first programmable waveguides, a plurality of core cells connected to each of the programmable optical coupler and the phase shifter to form a predetermined shape, the core cells being selectively driven by moving the optical signal from the predetermined shape according to the optical coupling efficiency and the phase, and an actuator electrically connected to one side of each of the plurality of core cells and configured to control the vertical movement and the horizontal movement.
