Algorithm-Enhanced Ultrahigh Resolution and Broadband Spectrometer Using Dual Subwavelength-Grating-Assisted Microring Resonators
We demonstrate a chip-scale spectrometer based on subwavelength grating microring resonators, achieving a bandwidth of 114 nm and a resolution of 40 pm. Using a spectral reconstruction algorithm, the resolution is enhanced to 10 pm.
