摘要： A compact optical circulator which can be expanded into a large number of optical ports is provided. For each port (1, 2, 3, 4), the circulator has an optical port assembly (10, 20, 30, 40) which has an end of an optical fiber (15, 25, 35, 45), a collimator subassembly (11, 21, 31, 41), and a birefringent crystal (12, 22, 32, 42). The collimator subassembly (11) collimates light from the optical fiber end (15) into a beam of collimated light and focusses a beam of collimated light to the optical fiber end (15) in a reverse direction. The birefringent crystal (12) is dimensioned and arranged with respect to the collimator subassembly (11) to split the collimated light beam from the collimator subassembly (11) into two parallel beams of light linearly polarized perpendicularly to each other, and to combine parallel beams of light linearly polarized perpendicularly to each other in the reverse direction into a beam of collimated light toward the collimator subassembly (11). The optical port assemblies (10, 20, 30, 40) are arranged in a linear array and a combination of polarization interfaces and planar relecting surfaces guide the light beams between the optical port assemblies (10, 20, 30, 40) so that the circulator can be designed with as many optical ports as desired.

摘要： A tunable optical filter of the Fabry-Perot interferometry type is provided. The filter has a pair of mirrors (12, 13) with reflecting flat faces facing and substantially parallel to each other. A tubular piezoelectric transducer (20) with a longitudinal axis (24) perpendicular to the mirror faces has an end attached to one of said mirrors (12, 13). A first electrode (22) is attached to the inner or outer surface of the piezoelectric transducer (20) and at least three, preferably four, second electrodes (23) are attached to the other surface of the transducer (2) so that the piezoelectric transducer (20) is located between the first electrode (22) and the second electrodes (23). Each second electrode (23) extends parallel to the longitudinal axis (24) and is spaced apart from each other in a plane perpendicular to the longitudinal axis (24). The faces of the first and second mirrors (12, 13) may be moved with respect to each other to maintain the mirror faces parallel to each other and to tune the filter by voltage signals.
