Title: Semiconductor laser and its manufacture
Inventor: MIYAZAWA SEIICHI
IPC: H01S5/00
Filed: 1988-01-22
Abstract: PURPOSE:To absorb damages of a semiconductor crystal caused by dry-etching for forming a ridge form and a stress caused by the difference in thermal expan sion coefficient between the semiconductor crystal and a surface protective film and realize the long life of a semiconductor laser with the ridge form by providing a semiconductor layer between a cladding layer and a surface insulating film. CONSTITUTION:A protective semiconductor layer 16 made of P-type GaAs is formed on a clad layer 13. The thickness of the semiconductor layer 16 is 0.3mum. The thickness is approximately uniform over the whole width. The semiconductor layer 16 is formed after the cladding layer 13 and an electrode contact layer 6 are partially removed by dry-etching. The layer 16 has an effect of absorbing crystal damages of the clad layer 13 caused by etching and improves the life because of the following two points: (1) defects existing in the recesses (thin parts) 15 of the cladding layer 13 are reduced by the growth of the protective semiconductor layer 16 and the long life can be realized, (2) a stress caused by the difference in thermal expansion coefficient between an insulating film (Si3N4 film) 7 and the clad layer 13 is absorbed so that the long life can be assured.

Title: Offset compensating circuit
Inventor: MARUYAMA TOSHIHIRO
IPC: H03F3/34
Filed: 1983-01-27
Abstract: PURPOSE:To extend the period used as an amplifier by connecting a capacitor switchingly from a feedback circuit side to an added circuit side at the amplifier operating period so as to shorten the time required for offset compensation. CONSTITUTION:A control circuit CON turns off switches S1, S3' and turns on S2, S3 at the compensating period and turns of the S1, S3' and turns off the S2, S3 at the amplifier operating period. Thus, since it is possible to keep a voltage across the capacitor C to a voltage V0 corresponding to the feedback amount during the compensating period, the amplifier operating period is made longer than that of a conventional system. Even if a value of a resistor Rf is selected smaller, since the voltage across the capacitor C is unchanged between the compensating period and the amplifier operating period, the compensating period is shortened.
