Subwavelength Racetrack Resonators With Enhanced Critically Coupled Tolerance for On-Chip Sensing

Subwavelength Racetrack Resonators With Enhanced Critically Coupled Tolerance for On-Chip Sensing

We propose a coupled-tolerant subwavelength photonic racetrack resonator (PRR) on the silicon-on-insulator (SOI) platform, in which a subwavelength grating (SWG) PRR is coupled to a symmetrical SWG bus waveguide. The material equivalent refractive index can be manipulated by the SWG characteristic a...
