| 英文摘要 | PURPOSE:To implement high gain and to facilitate temperature control, by forming a plurality of resonator-type optical amplifiers in a structure, wherein a plurality of resonator-type active-layer stripes are formed on the same semiconductor substrate, and providing optical isolators, which are inserted in an optical system or in an input or output system of light signals. CONSTITUTION:Active-layer stripes 201-210 are arranged. An inputted light signal is sent into the preamplifier active-layer stripe 202 through an optical isolator 301 as required. The amplified output is inputted to the active-layer stripes 204 and 206, which are connected in cascade. For the outputs of the active-layer stripes 202, 204 and 206, optical isolators 302, 304 and 306 are arranged. A control circuit 100 receives the output of the active-layer stripe 201 and outputs control signals, which control the gains, to the active-layer stripes 204 and 206. The output of the active-layer stripe 206 at the final stage of the AGC optical amplifier is inputted to the main-amplifier active-layer stripes 208, 209 and 210 through an optical isolator 306. The outputs of the active-layer stripes are combined in an optical coupler 400, and the result is outputted to an optical fiber transmitting path. |
