英文摘要 | PURPOSE:To reduce the magnitude of wet current, by reducing the difference in steps between the interface between an active layer and a clad layer and a junction plane, which stops the current. CONSTITUTION:On a substrate 1a, on which grating is formed, a guide layer 2, an active layer 3 and a P type InP layer 4a are formed. A stripe shaped SiO2 insulating film 13 is formed thereon. Then selective etching is performed. By using the substrate 1a as a stopper, the surface remains approximately flat. Then, a P type InGaAsP layer 7 and an N type InP layer 8a are grown, and a block layer 9a is formed. At this time, since the growing of the surface of the insulating film 13 is stopped, general height of the P type InGaAsP layer 7a is made higher than the P type InP layer 4. Even if the height is slightly changed, the height of the P type InGaAsP layer 7a at the side end of the insulating film 13 approximately agrees with the height of the P type InP layer 4a. At the N type InP layer 8a, the height of the side end of the insulating film 13 becomes the same. After the insulating film 13 is removed, a P type InP layer 4b and a contact layer 5a are grown, electrodes 11 and 12 are deposited and a DFB laser can be formed. |
