摘要： A multistage Mach-Zehnder interferometer type optical circuit including any number of symmetrical Mach-Zehnder interferometers and any number of asymmetrical Mach-Zehnder interferometers connected in cascade. In the optical circuit, low coherence light is used first to obtain individual phase control conditions of the symmetrical Mach-Zehnder interferometers without being affected by the asymmetrical Mach-Zehnder interferometers. Second, phase control conditions of the individual asymmetrical Mach-Zehnder interferometers are obtained by controlling the symmetrical Mach-Zehnder interferometers based on the first phase control conditions. Finally, the characteristic adjustment of the whole multistage Mach-Zehnder interferometer type optical circuit is carried out by controlling all the interferometers based on the phase control conditions of both the symmetrical Mach-Zehnder interferometers and asymmetrical Mach-Zehnder interferometers and setting the phase shift amounts of the individual interferometers at appropriate values.

摘要： An optical signal processor according to the present invention is an optical circuit of a lattice configuration. Its basic circuit structure comprises 3 dB directional couplers (9), two optical waveguides (1,2) with equal optical path lengths, and two optical waveguides (1,2) with different optical path lengths (an optical path difference of about 1 to 50 mm). Phase controllers (4) for performing phase shift are provided on the optical waveguides (1,2). The portions with equal optical path lengths function as variable directional couplers (3), and variable directional couplers (3) having arbitrary coupling rates can be constructed by changing the phase controllers (4) on the optical waveguides with equal optical path lengths. As for an adaptive filter (24), there is adopted a construction in which a photodetector (20) for withdrawing part of output is provided at the output port, and a feedback electric wiring (21) for feedback control is laid.
