摘要： A motion path search device includes a motion space identification unit which identifies, as first spaces, three-dimensional spaces passed through by a movable part in direct teaching operations performed by an operator, and a spatial difference calculation unit that calculates a first differential space that is a part of one of the first spaces identified as a result of one of the direct teaching operations and that has no overlap with another of the first spaces identified as a result of another of the direct teaching operations that precedes the one of the direct teaching operations. A feedback unit provides the operator with information regarding the first differential space, and a path search unit searches for a motion path of the movable part within a first accessible space resulting from combining the first spaces after the direct teaching operations.

摘要： In an external resonator type semiconductor wavelength tunable laser apparatus using a wavelength tunable mirror or a wavelength tunable filter which uses a refractive index change of liquid crystal, a resonant frequency is set as FR, when a response of the refractive index change to a drive voltage frequency of liquid crystal becomes maximum. A frequency F1 of a drive AC power supply voltage to control the refractive index of liquid crystal is set to a frequency largely different from FR. A wavelength tunable mirror or a wavelength tunable filter is driven with a signal in which a dither AC signal F2 of a frequency close to the FR and an AC power supply voltage are superimposed. A PD to monitor a light output from the laser controls an amplitude of the drive AC power voltage such that an amplitude of the dither AC signal F2 become minimum. Thus, high laser mode stability is realized.

摘要： The reflectance of a semiconductor optical amplifier (1) on the side where an external cavity is formed is 0.1% at most. The finesse value obtained by dividing the period of the transmission characteristic of the wavelength selection filter (3) by the half value width of the transmission characteristic is 4 or more and 25 or less. Even when the reflectance of a cavity side end face (1bb) of the semiconductor optical amplifier (1) is about 0.1%, a wavelength accuracy of ±1.5 GHz can be achieved by setting the finesse to 4 or more. In addition, a wavelength accuracy of about ±0.5 GHz can be achieved by setting the finesse to 8 or more. In order to suppress insertion loss, it is preferable to set the finesse of the FP etalon to 25 or less. This makes it possible to implement an external cavity wavelength tunable laser with high wavelength accuracy.
