Title: Semiconductor laser device
Inventor: TARUCHIYA SEIGO
IPC: H01S5/042
Filed: 1982-03-15
Abstract: PURPOSE:To obtain a semiconductor laser device which generates stable photo pulses even not by a power source of stable frequencies by a method wherein three kinds of semiconductors are laminated as clad layers of conductive type reverse each other, and the active layer at the middle therebetween, and electrodes are arranged so that the direct current generates a non-linear fluctuation in the active layer. CONSTITUTION:An oscillation vertical mode is caused by a method wherein the electrodes 7 are formed into a constitution wherein they are intermittent in the direction rectangular e.g. to the line O-O, and a direct current is supplied into the semiconductor layer 3 as the active layer of a semiconductor laser diode U via electrodes 6 and 7, and semiconductor layers 2, 4 and 5. Accordingly, a non-linear fluctuation is generated in the carrier density based on the direct current, in the semiconductor layer 3 as the active layer, by the non- linear interaction between vertical modes of the oscillation vertical mode, and thereby a non-linear fluctuation generates in the semiconductive dielectric constant as the active layer. Therefore, coupling polarization adjustment is generated, and accordingly the coupling between vertical modes of the oscillation vertical mode is generated.

CONSTITUTION:A time setting state detection switch S1 is driven so as to be turned ON and OFF by the time setting element mounted on the peripheral part of a dial rotating once a day. A day of the week altering switch S2 operates in conjunction with the dial to generate a day of the week altering pulse and a day of the week selection switch S3 selects seven days of a week. An operational processing part 5 is equipped with a power source circuit part 6 and takes-in the signals from the switches S1, S2, S3 to generate the signal pulse given to a relay performing the ON/ OFF driving of load at the set time of the selected day of the week. Further, the processing part 5 is provided with a control means for bringing the load to a non- driving state when the signal from the switch S1 changes to an OFF-state in such a case that the load is controlled so as to cross a day of the week bringing the load to a non-driving state through twelve o'clock midnight. By this method, though the setting of a day of the week can be set by the switch S3, thereby day-crossover control can be performed.
