High-Resolution Compact On-Chip Spectrometer Based on an Echelle Grating With Densely Packed Waveguide Array
We design a 121-channel on-chip spectrometer based on an echelle grating with densely packed waveguide array on 220-nm silicon-on-insulator platform. It offers a high spectral resolution of 0.5 nm in a 3 · 3 mm<sup>2</sup> footprint, covering a spectral range of 60 nm near the...
