Abstract

A monolithically frequency-stabilized 670-nm laser diode was described. The device has good power output and efficiency and can be thermally tuned with current injected into the grating region. The gain material consisted of strained InGaP quantum wells. A grating layer was then grown in the first epitaxial step just above the waveguide and holographic lithography was used to define a second-order grating only in the regions used for the rear mirror. Narrow index-guided single mode devices were then fabricated with two separate contacts on both the grating and the gain regions. The turn-on voltage was below 2 volts and the series resistance was about 3.4 Ohms with linear current-voltage characteristics. The thermal time constant was 10-50 μs.
