Abstract

PURPOSE:To obtain the stable, basic, lateral mode laser by providing a current blocking layer on both sides of a belt shaped mesa structure on an N type substrate so that said blocking layer is higher than said mesa structure, and embedding an active layer which is surrounded by a P layer characterized by a low refractive index and large inhibition handwidth in the groove formed by the mesa top and the blocking layer. CONSTITUTION:A belt shaped mesa 10, whose cross sectional area is of a trapezoidal shape and top side is of 4mum or less is formed in the (01-1) direction on the (001) surface of an N type InP substrate 1. A P<->GaP current blocking layer 2 is formed by reducing the temperature from 630 deg.C at a rate of 0.7 deg.C/min. for 120sec or less, in accordance with a liquid phase epitaxial method. At this time, nothing is grown on the top of the mesa, but, the layer 2 is grown on the surrounding surface so that the layer 2 is higher than the mesa 10. Then, an N<->InP clad 3, a nonadded InGaAsP active layer 4, a P<->InP clad 5, and a P<->InGaAsP can layer 6 are epitaxially grown consecutively. The compositions of the layer 4 and 6 are the same. Before the layer 3 is embedded in the groove 11 completely, the growing is stopped, the layer 4 and layer 5 are grown and embedded. In this constitution, light is confined in the layer 4, and the stable, basic, lateral mode oscillation can be obtained.
