Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To improve the optical coupling of an optical modulator with a semiconductor laser integrated part without generating the deterioration of the characteristics of a laser and the increase in insertion loss by a method wherein the optical modulator and the main significant part of the laser are constituted of a bulk layer or a quantum well layer of the same structure and the peak of the absorption spectrum of the modulator is made to differ from that of a laser gain. SOLUTION: A light guide layer 12 is grown and formed on a substrate 10 via a buffer layer 11 and thereafter, a quantum well structure, which consists of barrier layers 13 and well layers 14, is formed. Then, a light guide layer 15 is grown and formed on the quantum well structure, a diffraction grating 15a is grown and formed at the laser part and a clad layer 16 and a contact layer 17 are grown and formed in order on the layer 15. Then, a ridge and an electrode 18 are formed and the electrode between the laser part and an optical modulator part is etched away to separate electrically the laser part and the modulator part from each other.  Thereby, as the width of the electrode is narrow, the light source laser part has a high element resistance and at the time of current conduction, the peak of a gain spectrum of the laser part is shifted from the value of the peak at the time of drive of a low current into a DFB laser oscillation wavelength by the effect of heat generation and the laser part obtains a high luminous efficiency.

Title: Molding method of foamed resin
Inventor: MIZUNO TAMOTSU
IPC: B29C39/00
Filed: 1980-04-09
Abstract: PURPOSE:To eliminate the burr removing process and improve the efficiency of the molding work by a method wherein an elastic packing is provided at the abutting part of an upper mold and a lower mold and the foamed resin leaked out of the abutting part is cut off by the restoring force of the packing in case of the molding of the foamed resin. CONSTITUTION:In case of the molding of the foamed resin, a supporting plate 6 is provided at a position neighboring the outside upper end rim of the lower mold 2 and the elastic packing 7, provided along the outer periphery of the abutting part between the lower mold 2 and the upper mold 3 and consisting of a hollow cylindrical part 8 and a flat plate part 9, is secured to the supporting plate 6. When the resin is inserted into the mold frame 1 and is foamed, a part of the foamed resin 4 deforms the packing 7 and is leaked to the outside thereof due to the foaming pressure of the foamed resin 4. However, when the pressure of the foamed resin 4 is reduced, the continued condition between the foamed resin 4 in the mold frame 1 and the same at the outside of the mold frame 1 is cut off due to the restoring force of the cylindrical part 8 of the packing 7, therefore, the molded form, for which the burr removing work is not necessitated, may be obtained.

Abstract: PURPOSE:To reduce crosstalk between reproducing light beams and recording light beams by providing a detecting means, which is set so as to satisfy specific conditions. CONSTITUTION:The means, which detects third and fourth light beams separated by a pair of light refracting substances is set so as to satisfy an unequality d2<mdl when an interval on a recording medium of first and second light beams condensed on the recording medium is set at d1, the multiplying factor of an optical system provided between the recording medium and the means is set at (m), and the interval between the irradiated position of the respective light beams to irradiate the means and an edge part on a side where the second light beams of the means is approached is set at d2. That is, the range of a photo detector 45 is set so that is irradiated with only the reproducing light beams, namely, so that is not irradiated with the recording light beams, and simultaneously set in a range in which a position in the optical axis direction may be correctly tracking-controllable with the use of the beam spot of the reproduced light beams which irradiates the photo detector. Thus the crosstalk is prevented, and the information can be efficiently read and reproduced.
