Abstract

A two-wavelength emission laser (two-mode laser) has been fabricated using semiconductor quantum dots as the gain medium in the external cavity configuration. Two-mode laser emission with a separation of 98.8 GHz has been achieved by controlling the etalon and narrow-band filter setting. A 98.4 GHz beat signal was observed using the Michelson interferometer configuration, indicating that these emissions occurred simultaneously.
