摘要： A monolithic laser configuration has a substrate, a laser diode disposed on the substrate for generating a light beam, a photodetector disposed on the substrate in the path of the light beam for receiving at least one part of the light beam, and a deflection device disposed on the substrate for deflecting the light beam substantially perpendicularly to the substrate surface. The monolithic laser configuration can advantageously be used in a coupling module with a plastic SMT housing of a standard configuration, it being possible to produce the optical access through an opening in the leadframe of the coupling module.

摘要： This semiconductor laser diode module optically couples a laser diode and an optical fiber in which a fiber grating is formed, and a monitor photodiode for an optical output monitor is arranged at the rear of the laser diode. The semiconductor laser diode module improves the optical output characteristics at the optical fiber end versus the current of the monitor diode by setting the reflection center wavelength of the fiber grating to a longer wavelength than the oscillation center wavelength or the gain center wavelength in a laser diode.

摘要： A laser includes a gain medium located in a laser resonator. The gain medium generates plane polarized radiation plane polarized in a first polarization orientation. An electro-optical switch is located in the resonator. When the switch is activated the polarization plane of the laser radiation is rotated to a second orientation after making a forward and a reverse pass through the optical switch. When the switch is deactivated, the polarization orientation of the forward and reverse transmitted laser radiation remains about the same. A polarization selective device is located in the resonator between the electro-optical switch and the gain medium. The polarization selective device is arranged to permit circulation in the resonator of laser radiation in the first polarization orientation, and to restrict circulation of laser radiation in the second polarization orientation. The Gain medium is energized and the switch activated to allow energy to build in the gain medium. The switch is then deactivated to allow laser radiation to circulate in the resonator and deliver a laser pulse. A method of activating the switch by a sequence of DC pulses is disclosed.

摘要： A MEMS-based selectable laser output optical device (10) includes a laser source (12) having a laser output 14. A MEMS switch (16) is optically coupled to the laser source (12) for selectively coupling the laser output (14) from the laser source (12) in one of two directions (141) or (142). The MEMS switch (16) has a mirror (160) that is slidable or otherwise movable from a first position (161), where the mirror (160) is laying flat or in another non-obstructing position to provide a non-obstructing linear exit optical path (141). A second position (162) where the mirror (160) is in its upright vertically aligned direction, obstructs the linear optical path to re-direct the optical path in a non-linear direction.
