英文摘要 | PURPOSE:To enable an optical semiconductor device to be improved in FM modulation efficiency and optical output by a method wherein a DFB laser of low reflection and high reflection end face structure is divided into two parts in a direction of a resonator. CONSTITUTION:An InGaAsP guide layer 3 correspondent to the emitted light 3mum in wavelength, an active layer 4 of multi-quantum well structure, and a clad layer 5 are successively grown on a substrate 1 where a diffraction grating 2 has been formed. A buried layer is made to grow through a conventional process, then split electrodes 6 are provided, the substrate 1 is cut into unit elements, and a low reflection film 9 and a high reflection film 10 are provided to the end faces of the unit element respectively. The end faces are set to 0% and 95% in reflectivity respectively. Therefore, an integrated type optical semiconductor device which is high in optical output, variable in wavelength, high in efficiency, and flat in FM response property can be realized. |
