英文摘要 | PURPOSE:To make it possible to perform highly efficient continuous oscillation even at high temperature by forming a semiconductor layer whose forbidden band width is larger than the forbidden band width of a semiconductor substrate or a semiconductor constituting a light emitting region as a flat layer at the outer surface part of the light emitting region in at least one part of a current blocking layer which is formed at the peripheral part of an active layer. CONSTITUTION:This device has a P-InP clad layer 7 in the central part (groove 6) on a P-type InP substrate 1, a crescent type active layer 8 comprising InGaAsP and a part on an N-InP current block layer 9. An N-InP layer 3, a P-InP layer 3, P-In0.52Al0.48As4 a current block layer comprising N-InP layer 5 are sequentially formed on the both sides of the groove 6, i.e., the light emitting region, on the upper surface of the substrate The semiconductor layer 4 which is larger than the forbidden band width of InP is provided so as to block the current injection into the P-InP current block layer 2 from the N-InP clad layer 9. Therefore, the generation of leak currents is less even at high temperature, and the laser oscillation can be performed at high efficiency. |
