Title: Semiconductor ring laser device
Inventor: KUWABARA HIDEO
IPC: H01S5/00
Filed: 1978-08-24
Abstract: PURPOSE: To obtain an output if narrow oscillation spectrum and high strength by exciting one of two ring-like resonators combined with each other with respectively different wave lengths.  
     CONSTITUTION: On an n layer 11 on a p type GaAs 10, resonators 13 and 14 with respectively different wave lengths are formed on the sane surface and combined with each other. Degree of combination is appropriately set by selecting distance between them, thickness of the wave passage and the index of refraction. Excitation is made by providing an electrode 16 on the top surface of the resonator 13 and an opponent electrode on the rear surface of the base plate. Light is emitted in the neighborhood of a pn joint and the resonator 13 generates a resonant spectrum at a cycle if Δλ 1 , and the resonator 14 which is combined with the resonator 13 generates a resonant spectrum at a cycle of Δλ 2 . For this reason, of these two resonant spectra, only those whose wave come together on the frequency axis and which are within gain width G of the ring laser are taken out through a wave passage 15 for outout. And therefore, number of oscillation vertical mode becomes within a range of one to several pieces and a large output is obtained because spectrum becomes very narrow and concentrated.

Title: Optical pick-up device
Inventor: UCHIBORI HIDEO
IPC: G11B7/12
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the degradation of performance from being generated due to a temperature change by interposing a deformation absorbing member, for which the friction coefficient of a surface is enlarged, between a detector plate, to which an optical detector is mounted, and an optical unit. CONSTITUTION:A deformation absorbing member 14 is interposed between a detector plate 2 and an optical unit 3 and fastened by a fixing screw 4. As a result, vertical resistance 8a and 8b and reaction force 9a and 9b is operated to a contact surface 13a between the detector plate 2 and deformation absorbing member 14 and a contact surface 13b between the deformation absorbing member 14 and optical unit 3. When the temperature change is operated to such an optical pick-up device, cutting force 10a and 10b is operated to the contact surfaces 13a and 13b so that parts can be mutually dislocated. However, since the friction coefficient is large between the deformation absorbing member 14 and contact surfaces 13a and 13b, fixing force 12a and 12b goes to be larger than the cutting force 10a and 10b due to a thermal expansion coefficient. Then, even when adhesive agent is not used, the parts are not mutually dislocated. Thus, the degradation of the performance can be prevented from being generated by the temperature change.
