摘要: In an ultrahigh-speed clock extraction circuit wherein a local pulse generating light source 22 for generating a local optical pulse stream synchronized in bit phase with an input optical signal pulse stream is placed in a phase-locked loop, when repetition frequencies of the input optical signal pulse stream and the local optical pulse stream bear a particular relationship, a frequency demultiplier 32 and multipliers 43 and 52 are set so that the frequency of a modulation signal for an optical modulator 41 and a frequency which is a natural-number multiple of the modulation signal frequency, and the frequency of a down-converted version of an optical pulse stream output from a photodetector 42 differ from each other.

摘要: A phase-lock loop is formed by a voltage-controlled oscillator, a local optical pulse source, an optical branching device for branching the locally generated optical pulse stream from the local optical pulse source, a harmonic component local generation part for locally generating a harmonic component electrical signal from the one of two branched locally generated optical pulse streams, and a phase comparison part for comparing the phases of the locally generated harmonic component electrical signal and an incoming signal component electrical signal generated from an incoming optical signal pulse stream and for supplying the voltage-controlled oscillator with a control voltage corresponding to the phase difference between the two input electrical signals. The other branched output from the optical branching device is output as a locally generated optical pulse stream bit-phase synchronized with the incoming optical signal pulse stream.

摘要: A movable beam (182a) and a movable beam (182b) each having one end fixed to a frame portion (181) of a mirror substrate (108) are provided inside the frame portion (181). The movable beam (182a) and the movable beam (182b) each having one end fixed to a corresponding to one of two opposite inner sides of the frame portion (181) are aligned at a predetermined distance on the same line in the direction in which the two sides face each other. Each of the movable beam (182a) and the movable beam (182b) has the other end displaceable in the normal line direction of the mirror substrate (108) and therefore has a cantilever structure. A mirror (183) is arranged between the movable beam (182a) and the movable beam (182b) and connected to them via a pair of connectors (109a, 109b).

摘要: A light-shielding portion (10) shields the light spot of output light output toward a shunt position α by a projecting portion (12). Hence, the output light output toward the shunt position α does not travel to an output port (111). This allows to prevent crosstalk.
