Summary :

An array of monolithically integrated composite-cavity lasers which has been fabricated on the basis of the chemical etching technique is reported. Each composite-cavity laser consists of a laser and an external reflector, and the reflector is used also as a photodetector. The array is designed so that each laser can be operated independently of the other for parallel processing of optical data with high stability operation and independent monitoring capability. Experimental devices have been successfully fabricated.
