    摘要： This invention pertains to a multipass retroreflector and to a method for its operation. In a preferred embodiment, the retroreflector comprises three reflecting surfaces arranged at an angle to each other in the form of a prism that is triangular in cross-section and 1 to 2 ports through which an optical beam enters and/or exits. The method includes the step of admitting an optical beam into the retroreflector where the optical beam is reflected from the reflecting surfaces and exits parallel to the path of the incoming optical beam. The method also includes the steps of spacing and adjusting angular disposition and dimensions of the reflecting surfaces in order to change path length of the optical beam passing through the retroreflector. This spacing can be continuously scanned causing a large change in optical path length due to a small change in the position of the moving surface.

    摘要： A method and system for modifying the detected phase of a signal by driving a photodetector into saturation. This system and method differs from current manual and electrical microwave phase modification by using saturation means for modifying the phase. The system and method may use a plurality of the signal generators for saturating the photodetector.

    摘要： A multiple wavelength laser apparatus is taught to select wavelengths for simultaneous generation of short pulses at multiple wavelengths having application in wavelength-division-multiplexed communications systems, photonic microwave systems, and pump-probe applications. The multiple wavelength laser comprises an optical fiber lasing material, a laser pump source connected to said lasing material for outputting coherent light, a splitter for dividing said coherent light into parallel paths of differing wavelengths, parallel band pass filters for selecting multiple wavelengths, and parallel Faraday mirrors for operating the multiple wavelength laser in a single polarization state.
