| 英文摘要 | PURPOSE:To easily obtain an optical logic element forming plural logic elements on one and the same substrate and capable of complex operation by constituting a resonator in a semiconductor of an optical waveguide equipped with diffraction gratings and mutually connecting plural semiconductor lasers. CONSTITUTION:A laser A controlled by current flowing into a p-electrode 1a has a resonator consisting of diffraction gratings 4a, 4b and is called as a distributing Bragg reflection type laser and a laser B controlled by the current flowing into a p-electrode 1b constitutes its resonator of diffraction gratings 4b, 4c. Both the lasers A, B are coupled with each other through an optical waveguide consisting of a p-clad layer 3 having the diffraction grating 4b, and active layer 5 and an n-clad layer 6. When the laser A is ON, light is injected from the optical waveguide into the laser B and laser oscillation can be easily generated. When current expressed by Ib=Ib0 (Ib0 is the intermediate value of threshold current values of the laser B) is biased for instance, the optical output of the laser B is controlled by the ON and OFF of the laser A. Consequently, many optical logic elements can be integrated on the same substrate without requiring the accurate alignment of lenses. |
