Abstract
PURPOSE: To stabilize laser operation through confining injection current and oscillation photowave effectively in an active area by creating the active area on the top of a band projection of semiconductor substrate and giving electrode only on the top of the said projection.
CONSTITUTION: Semiconductor thin films 2∼5 varying in composition are created in heteroconstruction on a semiconductor substrate 1 having a band projection 8 along the said projection 8, and an electrode 7 is formed on the projection 8 at the same time. The thin films 2∼5 comprise an active layer 3 having laser gain and clad layers 2, 4 to confine injection carrier and laser beam in the active layer 3, and there is formed PN junction at the interface of the active layer 3 and the clad layers 2, 4. The active layer 3 formed on the projection 8 therefore becomes a band photoconductor horizontally which is surrounded by the clad layer 4 and confines both photowave and carrier accordingly, thus stabilizing the oscillation mode.
