Title: Semiconductor laser element
Inventor: HOSODA MASAHIRO
IPC: H01S5/00
Filed: 1985-09-18
Abstract: PURPOSE:To control out the position where a defect is created from a laser operation part and improve crystallinity of an exciting part and improve reliability and reproducibility of a semiconductor laser by forming grooves on a semiconductor substrate for crystal growth. CONSTITUTION:Two reverse mesa-shape grooves 7 are formed on an N-type semiconductor substrate 1 on the left and right sides. An N-type AlGaAs cladding layer 2, a nondoped InGaAsP active layer 3, a P-type AlGaAs cladding layer 4 and an N-type GaAs cap layer 5 are successively laminated on the substrate 1 to form a multilayer crystal structure for laser oscillation with double-hetero structure. As the cladding layer 4 and the cap layer 5 are joined with opposite polarity, a current is not applied. Then a Zn diffused layer 6 is formed at the center part between the two grooves 7 from the surface of the cap layer 5 to the depth reaching the cladding layer 4. The region of this diffused layer 6 is converted into a P-type region and the current is concentrated. If a laser oscillation operating part is provided in the active layer 3 directly below the diffused layer 6, defects created in the InGaAsP active layer 3 are concentrated to the parts 8 above the reverse mesa-shape grooves 7. In other words, fine crystals or the like created in the molten liquid before the growth are attracted to the grooves 7 and an exciting part 9 becomes a part with satisfactory crystallinity.

Filed: 1984-10-05
Abstract: PURPOSE:To compensate aberration efficiently over the whole screen by constituting the 2nd lens group of the 2-1th meniscus-like lens turning its convex surface to an object side and having a negative refractive power and the 2-2th meniscus-like lens turning its convex surface to an image side and having negative refractive force which are arranged successively from the object side. CONSTITUTION:The 2nd-lens group is constituted with two lenses having the negative refractive force so that a lens having positive refractive force is not included, Petzval's sum is prevented from an increase in a negative direction and the variation of a curve on the image surface is reduced over the whole power modification range. Since the negative meniscus lens turning its convex surface to the object side and the negative meniscus lens turning its concave surface to the object side are symmetrically constituted each other, the aberrations of respective lenses are offset each other and the generation of the aberration can be suppressed at a small level. Consequently, a small zoom lens reducing the variation of the curve on the image surface due to a power modification and efficiently compensating the aberration over the whole screen can be obtained.
