Title: Semiconductor laser and manufacture thereof
Inventor: OKUDA TETSURO
IPC: H01S5/00
Filed: 1993-04-21
Abstract: PURPOSE:To obtain a low-distortion semiconductor laser for analog modulation at a high yield by a method wherein regions, where diffraction gratings are formed, are biased on the side of the front surface of a resonator and one of diffration grating regions is separated from the end face of the resonator. CONSTITUTION:A photoresist 21 is applied on an InP substrate 20 and a resist pattern is exposed by a two-luminous flux interference exposure method. Then, the resist 21 is closely exposed and developed using a mask 24 of such a mask pattern as to perform an exposure only on a region, where diffraction gratings are not formed, of the resist 21, whereby a pattern formed partially with the diffraction grating is formed. The pattern is etched using this resist pattern as a mask and the diffraction gratings 25 are formed. In this case, the coupling coefficient of the diffration grating on the side of the end face of a resonator is large and is made small in the interior of the resonator, whereby a field intensity distribution is made uniform. Accordingly, a current-light output characteristic linearity is improved and the mutual modulation distortions of the gratings 25 are reduced.

The container of the resin soln. is housed in a sealing chamber which can be evacuated. Then the sealing chamber is evacuated to -600 to -700mmHg reduced pressure and held for about one minute to perform first impregnation. Then the inner pressure of the sealing chamber is made to normal pressure and the raw body in the soln. is taken out. Next, the raw body is put in a resin soln. of silicon resin and toluene with 1:9 weight ratio and treated for second impregnation in the same way as in the first stage. Then third impregnation is performed with a resin soln. having silicon resin to toluene ratio of 1:19. After impregnation, the raw body is taken out from the soln., naturally dried at room temp., and then cured at about 150 deg.C for about 2 hours.

IPC: C22F1/18
Filed: 1987-04-16
Abstract: PURPOSE:To provide high strength and high ductility and also to reduce the dispersion of their values, by subjecting and alpha+beta-type Ti alloy to hot working, rapid cooling, and annealing treatment under temp. conditions in specific ranges, respectively, and by properly growing a beta-phase. CONSTITUTION:An alpha+beta-type Ti alloy is hot-worked at a temp. between the beta-transformation point (betat) and betat-60 deg.C (not including betat and betat-60 deg.C) into the prescribed shape, which is cooled rapidly before the temp. of the Ti-alloy material falls down below betat-60 deg.C to form a residual beta-phase or martensite. After rapid cooling treatment, annealing is applied at 600-800 deg.C to properly grow a beta-phase precipitated from martensite and the residual beta-phase. By this heat treatment, the alpha+beta-type Ti alloy combining high strength with high toughness and reduced in the dispersion of their values can be obtained, and further, the process can be simplified because the need for heat treatment for solution heat treatment is eliminated.
