Optical black hole characteristics using microring space‐time distortion circuit

An optical black hole circuit designing and modeling using microring Kerr effect within the microring resonator system is proposed. An InGaAsP/InP material other than metamaterials are employed for optical black hole generation. The input sources are the space-time function modulations, where the resonant space-time distortion of the electric field propagation through the circuit can be arranged to meet the balanced optical path differences. The nonlinearr Kerr effect can be generated by the two side rings and induced into the center ring. The optical black hole circuit characteristics are investigated from the event horizon to the singularity area, where the potential for a high-performance light absorber can be envisaged. In applications, the device can be employed in photovoltaics and quantum technology.
