| 英文摘要 | PURPOSE:To enable a high saturation light output intensity to be obtained even if an active layer of an isotropic waveguide structure is used by providing a plurality of mutually independent current injection areas in parallel to light axis of an active layer. CONSTITUTION:A signal light 19a with a wavelength of 55mum to be amplified is allowed to inside an inciding edge 17a through means such as a fiber and is coupled to an active layer 12. If current is allowed to flow by applying forward biased voltage between electrodes 15a and 16, gain corresponding to the number of injected carriers is generated within an active layer 12. Thus, the inciding light 19a advances toward an radiation edge 17b while being amplified but current can be injected into the electrode 15b independently from the electrode 15a since the electrode 15b is electrically separated from the electrode 15a. Since this kind of operation can be performed regardless of the shape of the waveguide path, a light amplifier with low inciding deflection light dependency and high saturation light output strength can be obtained if it is applied to a light amplifier with an isotropic active layer. |
