Large Free Spectral Range Optical Filtering with Engineered Multi-Mode Asymmetric Grating
A compact 1D-asymmetric silicon photonic-crystal is designed for a significantly large free-spectral-range via intermodal interference. The device demonstrates efficient optical filtering, boasting a substantial extinction ratio of 20dB and a moderate group index of 15.
