Abstract :
A new composite-cavity (GaAl)As laser comprising a monolithically integrated pair of a laser and reflector has been developed on the basis of the chemical etching technique reported by the present authors. The rear facet of the laser and the reflector are separated by a small air gap. As a result, the new laser showed low threshold and high mode stability operation without mode jumping in a temperature range as wide as 25°C.
