Abstract
A short-cavity (GaAl)As stripe geometry laser with a threshold current of 30 mA has been fabricated by a new chemical etch process which uses a multilayer metal mask. The laser is 23 ¿m long and 12 ¿m wide, and does not have reflective coatings on the etched facets. Quasi-single-mode operation is obtained in pulsed conditions.
