英文摘要 | PURPOSE:To facilitate manufacture and achieve optical coupling efficiency of about 100% by causing a light emitting region to include an active layer consisting of multiple quantum well structure and causing a light modulating region to include a semiconductor layer in which multiple quantum well structure is randomized. CONSTITUTION:A distributed feedback type semiconductor (DFB) laser region 100 includes an active layer consisting of a semiconductor layer (MQW layer) 30 with multiple quantum well structure, and a modulator region 200 includes a semiconductor layer (MQW randomized layer) 40 in which multiple quantum well structure, same as that of the active layer, is randomized. DFB laser light can be modulated by applying an electric field to the MQW randomized layer 40 due to Franz-Keldysh effect. Because the MQW randomized layer 40 is optically continuously connected to the original MQW layer 30, optical scattering is scarcely found at the boundary part between the DFB laser region 100 and the light modulator region 200 so that coupling efficiency of nearly 100% can be achieved. |
