| 英文摘要 | PURPOSE:To obtain stable single longitudinal mode oscillation, by the constitution wherein an optical waveguide is intersected with light emitting surfaces at an angle other than a right angle, and suppressing the oscillation in a Fabry- Perot resonating mode. CONSTITUTION:Grooves are formed in an N type InP substrate 11 in a stripe shape. On one surface of both sides of the groove, a diffraction grating made of periodic concave and convex parts is formed so as to cross the direction of the groove at a right angle. On said grating, an N type layer 12, a nondoped P1-z layer 13, a P type layer 14, a P type InP layer 15, and an SiO2 film 16 are provided. Said layers are held between metal electrodes 17 and 18. In this laser, the grooves formed on the substrate and the waveguide 19 are intersected with the light emitting surface 20 and 21 at an angle other than the right angle. In this constitution, the oscillation threshold value in the Fabry-Perot resonating mode is increased, and the operation in the Fabry-Perot resonating mode when the operation is performed in the distributed feedback oscillating mode can be suppressed. |
