摘要： The optical fiber coupling apparatus (1) for coupling light from a light-emitting device (3) into an optical fiber (4) in an optoelectronic package comprises a microactuator (8) for positioning the end of the fiber (4) with respect to the light-emitting device (3), and a control circuit (9) in which the manipulated variable is a position of the fiber end. The control circuit (9) comprises outcoupling means (41) for coupling out of the fiber (4) a well-defined portion of the light propagating through the core of the fiber (4) and a photodetector (5) for detecting the intensity of the outcoupled light portion. The controlled variable in the control circuit (9) is the light intensity detected by the photodetector (5), from which a microprocessor (6) calculates command signals for the microactuator (8). Thus, a remote control of the optical coupling without any external intervention is achieved.

The adjustable positioning mechanism comprises a reference plate having a predetermined shaped socket providing a reference mating surface, and a mobile member for holding the optical element. The mobile member has a shaped mating portion at least part of which is defined by a spherical surface adapted for fitting into the reference plate socket and abutting against the reference mating surface, thereby providing a pivot type of joint between the reference plate and the mobile member. The adjustable positioning mechanism is also provided with a deformable maintaining element connected to the mobile member acting against the reference plate and adapted to rotatively hold the mobile member and the reference plate together in cooperation with the pivot joint. The adjustable positioning mechanism is also provided with a releasable non-deformable securing element connected to the mobile member frictionally acting against the reference plate for rigidly securing the mobile member and the reference plate together when the securing element is in a locked position. The adjustable positioning mechanism also comprises non-deformable tilt adjustment means connected to the mobile member and pressing against the reference plate for providing a controlled angular movement of the mobile member relative to the reference plate when the securing element is in an unlocked position.

摘要： The present invention relates to a dispersion compensating module or the like having a simple and compact structure. The dispersion compensating module comprises a plurality of dispersion compensators between its input and output ends and at least one or more optical switches disposed between these dispersion compensators. Each of the optical switches acquires signals reached from its first port and is switching-controlled so that the signals are outputted from one of its second and third ports. The dispersion compensating module controls the port switching operation of at least one of the optical switches, thereby adjusting the propagation line of the signals, i.e., the dispersion compensation amount. In this manner, the dispersion of the signals which reached the input end of the dispersion compensating module is compensated for by an amount determined in accordance with the installation position of the optical switch in which port switching is to be performed, and the dispersion-compensated signals are outputted from the output end of the dispersion compensating module.
