    摘要: A semiconductor laser array includes a pair of regions of an active layer for emitting laser lights being provided so as to produce a predetermined angle therebetween; the respective regions of the active layer being provided so as to have TE wave electric field vectors of different directions from each other in a plane vertical to the emitting direction of the output laser light. As such, laser light emitted from each of the active layer regions can be used independently without interference from the other.

    摘要: A semiconductor laser device comprises a semiconductor laser portion (17) including a double hetero structure and a vertical MIS-FET portion (18) form on, and in series with, the semiconductor laser portion (17). The vertical MIS-FET portion (18) includes an n-type GaAs layer (6), a p-type GaAs layer (7), an n-type GaAs layer (8), and a striped groove (31) having V-shaped cross-section formed from the top surface of the n-type GaAs layer (8) to the n-type GaAs layer (6). A metal gate electrode (11) is further provided on the top surface of the striped groove (31), on an insulating film (10). A current (41)flowing through the vertical MIS-FET portion (18) is changed according to a photo modulating signal applied to the metal gate electrode (11) and, a current (40) is also changed according to the current (41). Accordingly, a laser oscillation output of the semiconductor laser portion (17) is also changed to accomplish the optical output modulation of the semiconductor laser.
