Abstract
The development of GaSb-based laterally-coupled distributed feedback diode lasers by means of cost-effective nanoimprint lithography process is presented. The separate confinement laser gain structure comprised two In0.2GaSb quantum wells. A grating pattern was defined and etched on the sides of the laser diode waveguide to enable distributed feedback. At room temperature the lasers emitted ~2mW output power in a single longitudinal mode at ~1945nm and exhibited a sidemode suppression ratio of over 30dB. A temperature dependent wavelength tuning coefficient of 0.16nm/°C was measured for the laser output.
