Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/00
Filed: 1981-07-07
Abstract: PURPOSE:To oscillate a semiconductor laser in a stable fundamental lateral  mode by forming a V-shaped groove on a multilayer semiconductor layer and  forming an active region therein, thereby preventing the leakage current. CONSTITUTION:Three clad layers, i.e., an n type buffer layer 11, a P type block layer 12 and a current reducing n type clad layer 13 are sequentially grown on an n type InP substrate 10. Thereafter, a V-shaped groove is formed in the clad layers formed of the three layers. The depth of the groove is formed to the degree to produce only the fundamental lateral mode in the length (the width of the active region 15) of the bottom side of an inverted triangular active region 15 formed on the bottom of the groove to coincide with the surface of the layer 12, i.e., the boundary between the layers 12 and 13 to the surface. Subsequently, a P type clad layer 16 and a cap layer 17 are continuously grown, a Cd diffused region 18 is formed, thereby obtaining the desired semiconductor laser.

Filed: 1982-06-18
Abstract: PURPOSE:To transmit a local key signal with less number of connecting line by converting an output of plural local keys into serial signal and ORing a receiving output of a remote control signal and the serial signal on one connecting line. CONSTITUTION:An output of the local keys 10-25 is converted into the serial signal at a key matrix encoder 33 and applied to an OR circuit 35 together with an output signal of a photo diode 27 receiving the remote control signal. The output of the OR circuit 35 is applied to a microprocessor 1 for load control via the connecting line 26. The format of the serial signal is constituted the same as the output format of a remote control transmitter (not shown) and the microprocessor 1 processes similarly both the signals. Thus, terminals which have been used for the reception of the local key signals of the microprocessor 1 are used effectively as other input and output ports.
