Title: Semiconductor laser device
Inventor: SAITO SATORU
IPC: H01S5/026
Filed: 1988-03-29
Abstract: PURPOSE:To control an emitting light volume easily with voltage and constrict an injection path of a drive current so as to emit light rays efficiently by a method wherein a laser rays generating section and a FET type transistor section are laminated on a substrate in a direction perpendicular to the substrate. CONSTITUTION:When a voltage is applied to an electrode 1, the current injected into a cap layer 4 is injected into an active layer 6 as being concentrated owing to the shape of an upper part. In this process, emitting light rays are trapped with clad layers 5 and 7, and the current flowed through the active layer 6 flows toward a substrate 8 through a current path constricted by the gate 9 of a FET 12. Therefore, the current injected into the electrode 1 spreads near the active layer 6 and then is concentrated to flow as shown by an arrow 16. The current intensity can be controlled by varying a depletion layer 10 generated at the substrate 8 through the gate 9 as a voltage applied to a gate electrode 3 is changed.

The circuit consists of transistors(TRs) 11, 12, the gate and source being the inputs are connected in parallel with the output circuit 2 and the circuit is operated simultaneously. Since no load is connected to the dummy output circuit 3, only a through-current iA2 flows to the TRs 11, 12. The current iA2 is proportional to the area ratio of the TR 11 and a TR 209 and the area ratio of the TR 12 and a TR 308. When the area ratio is the unity, the relation of iA1=iA2 exists and the iA1 is extracted indirectly by detecting the current iA2.
