英文摘要 | PURPOSE:To reduce the occurrence of leakage currents so as to increase the optical output of the title laser and widen the wavelength variable width by inverting a laminated n-type semiconductor contact layer and semiconductor current blocking layer to p-type and bringing an n-type semiconductor base layer into contact with the n-type semiconductor contact layer. CONSTITUTION:InGaP tuning layer 4, n-type InP base layer 5, active layer 6, the first p-type clad layer 7 are formed by selective growth. All of an n-type InGaAsP contact layer 11, p-type current block layer 13, and n-type current block layer 14 which are grown after an SiO2 film is removed are formed of InGaAsP similar to the layer 7 and the layer thickness on the (111) B plane is made extremely thin. In addition, the n-type layers formed on the (111) B plane are inverted to p-type so that the layers do not interfere with a laser driving current 41 flowing to the first clad layer 7. |
