Suppression of avoided resonance crossing in microresonators
Kerr frequency comb generation in microresonators is enabled by notable developments in fabrication technology and novel nonlinear material platforms. However, even in a low loss and highly nonlinear microresonator, the avoided resonance crossing may hamper reliable frequency comb generation. We present a method to suppress the avoided resonance crossing induced by polarization mode coupling.
Our approach employs a filter waveguide coupled to a microring resonator for selective filtering of the TM00 mode while keeping the operational TE00 mode with low loss. We experimentally demonstrate an avoided-crossingsuppressed microresonator in the AlGaAs-on-insulator platform.
