摘要: We demonstrate record high temperature operation, 400 °C, of an integrated Al 2 O 3 :Er3+ DBR laser on ultra-low-loss Si N 4 waveguide platform. Additionally, the device exhibits uncompensated dependent wavelength shift 1.92 GHz/°C and maintains over 1.5 mW output power throughout entire range.
