Silicon Nitride/Silicon Dioxide Echelle Grating Spectrometer for Operation Near 1.55 μm
Here we use an electron beam lithography system to pattern an Si<sub>3</sub>N<sub>4</sub>/SiO<sub>2</sub> echelle grating using silver as a reflector on the grating grooves. The grating in this letter achieves 1.39 dB on-chip loss, a spectral resolution of ~1300,...
