Abstract
A buried heterostructure laser diode and method for making the same wherein an active layer is provided in a semiconductor region forming a mesa stripe, and, except for the top surface portion of the mesa stripe, the side surface portion of the mesa stripe and the remainder are covered by a current-blocking layer. Furthermore, a current-confining layer covers only this current-blocking layer, and a clad layer covers the current-blocking layer and the top surface portion of the mesa stripe.
