| 英文摘要 | PURPOSE:To enable fast response by controlling light which transmits through an optical resonator with light propagating in an optical waveguide. CONSTITUTION:By injecting light Pin into a vertical resonator 2 through a transparent electrode 24 on the upper surface of an element, transmission output Pout vs. laser current I1 by an optical waveguide 1 parallel to the substrate is obtd. This output Pout increases gradually over the threshold current (I1th100mA), drastically increases after saturation of absorption of the absorbing layer, and then maintains almost constant. In this state with low voltage, switching of light can be done without applying high voltage. The switching speed of the laser comprising the optical waveguide parallel to the substate is equal to that of usual semiconductor lasers. The switching speed of the transmitted light depends on the switching speed of the laser and same switching speed is confirmed. Thereby, fast response can be obtd. without requiring high vias voltage. |
