摘要： An interferometer includes a means for splitting, at a splitting location, an input light beam into a first beam and a second beam; and means for recombining, at a recombination location, the first beam and the second beam. The interferometer is designed such that the first beam will travel a first optical path length (OPL) from the splitting location to the recombination location, and the second beam will travel a second OPL from the splitting location to the recombination location and such that when the input light beam has bean modulated at a data rate comprising a time interval, then the difference in optical path lengths between the first OPL and the second OPL is about equal to the time interval multiplied by the speed of light.

摘要： A parallel glass plate mounted on a rotating fixture is used to precisely control the optical path length of a light beam. The glass plate refracts the incident optical signal to increase the length of its optical path as a function of the angle of incidence. The device can easily achieve a precision in the order of nanometers and is particularly suitable to fine tune the cavity length of a resonator and the optical path difference of an interferometer. Accordingly, the preferred application of the invention is in an interferometric interleaver. The glass plate can also be coated with a partially reflective coating to attenuate the optical signal passing therethrough. By judiciously selecting the refractive index, the thermal coefficient of refraction, and the coefficient of thermal expansion of the glass, thermal effects may be virtually eliminated.

摘要： An opto-electronic device is provided wherein an optical assembly having a first coefficient of thermal expansion is connected to a substrate having a second, different coefficient of thermal expansion. A plurality of stakes are either separately inserted or integrally formed-in the optical assembly and extend through and are adhesively bonded to passageways formed in the substrate. The stakes reduce or prevent differential thermal expansion that would otherwise occur as the device heats up during operation. The substrate may be thermally connected to a metallic housing for the device to increase transfer of unwanted heat into the ambient atmosphere.
