摘要： A fibre optic switch which includes an actuator reversibly movable between at least two switch positions, an actuator position detector and a single optical fibre path connected between the actuator and the actuator position detector. A beam splitter is provided to couple light from a light source into the fibre so as to travel towards the actuator. A filter is selectably insertable into the path of light emanating from an end of the fibre at the actuator and a retro-reflector reflects the filtered light back to the fibre. The reflected light is directed by the beam splitter towards the actuator position detector.

摘要： In an optical path control device 100, dispersed lights L2 in a flat shape in which a spot size in an arrangement direction (y-axis direction) of light deflection component elements to deflect light is relatively larger enter a light deflection element 7 and thus, the dispersed lights L2 can be deflected precisely and efficiently. Particularly in the optical path control device 100, the spot size thereof is converted by an anamorphic converter 2 arranged prior to the dispersive element 5. Thus, the degree of flexibility of optical design can be increased such as being able to arrange various optical components subsequent to the dispersive element 5.

摘要： An optical switch actuator moving an optical element into or out of an optical pathway. The optical element is coupled to a movable shuttle and driven by a motor between two rest positions. The motor includes two stationary coils and a magnet. The shuttle is magnetically latched in the rest positions. The optical element's position at the extended rest position is controlled with a stop that contacts the shuttle to provide accuracy and precision about multiple axes. The material used to construct the actuator's components aids in repeatedly positioning the optical element with precision.

摘要： Methods of manufacturing a MEMS assembly having a shutter or mirror driven by an actuator. The MEMS assembly can be formed by grooving a substrate, forming a displaceable member and electrode actuators on the substrate, and joining to a supporting base. Alternatively, the mirror core and the electrode actuators can be formed on separate substrates and thereafter be joined. A MEMS actuator which moves the member in a direction perpendicular to the MEMS actuator's own plane has interlaced internal ridges. When voltage is applied to the ridges, the actuator's upper and lower substrates move together.

摘要： A highly reliable optical communications equipment is offered, which can control light more accurately than heretofore (i.e., less restrictions are imposed on the amount of attenuation and on the resolution) and which is equipped with a latching function. The optical communications equipment includes a piezoelectric actuator, a moving body moved by the piezoelectric actuator as a drive source, a multi-coating filter for controlling light that is a signal medium by movement of the moving body, a drive circuit for controlling the position of the multi-coating filter via the actuator, and a control circuit. The piezoelectric actuator uses bending vibrations produced in a piezoelectric vibrating body as a power source. If the moving body is not moved for a given time, the control circuit sends a function keeping signal to drive the actuator to such an extent that the moving body does not move. Thus, the function of the actuator is maintained.
