Abstract
Optical frequency combs have become essential components in a wide variety of technologies, with semiconductor laser diodes becoming increasingly relevant due to their seamless integration with photonic circuitry. We study the high temperature operation of a single-mode, passively mode-locked ridge waveguide laser based on InAs/InP quantum dashes designed for C-band operation. We present experimental evidence of stable optical frequency comb generation at temperatures up to 85°C, with peak widths of the repetition rate below 10 MHz. When deployed in high temperature environments, these devices can offer power savings of up to 80%.
