  • Publication number: 20140241731
    Abstract: A free space optical communication system (10) including first and second mono-static transceivers (20a, 20b). Each transceiver (20a, 20b) includes a reflective assembly (40) defining a reflective surface (44) about a receiving end of a respective optical fiber (32) and configured to reflect optical signals (26) within a field of view of the transceiver (20a, 20b) as a modulated retro-reflective signal (28). Each mono-static transceiver (20a, 20b) includes an acquisition system (60) configured to detect a modulated retro-reflective signal (28) and adjust the alignment of the respective transceiver (20a, 20b) in response to a detected modulated retro-reflective signal (28). A mono-static transceiver and a method of aligning a mono-static transceiver are also provided.

  • Publication number: 20110284728
    Abstract: An imaging system (300) is provided. The system includes a second harmonic generator (308) for receiving a source photon beam of a first wavelength and generating a sensor photon beam of the first wavelength and a pump photon beam of a second wavelength that is one half of the first wavelength. The system also includes an amplifier (202) for receiving a signal photon beam and the pump photon beams and producing an amplified photon beam of the first wavelength, where a number of photons in the amplified photon beam being greater a number of photons in the signal photon beam and the signal photon beam includes a portion of the sensor photon beam reflected from a target (318). The system further includes at least one photon counter (204) configured to receive and detect at least a portion of the photons in the amplified photon beam.

  • Patent number: 6415079
    Abstract: The present invention is predicated on applicants' discovery that an appropriately spaced and dimensioned internal gap cladding can substantially reduce short wavelength cladding mode loss in a fiber Bragg grating. A fiber Bragg grating is provided with a ring of closely spaced, longitudinally extending gap regions in the glass peripherally surrounding the core. The gaps are spaced apart by thin glass webs having a thickness less than a wavelength of the light being transmitted and are disposed peripherally about the core at a distance of 2-10 wavelengths from the core center. The thin webs limit the passage of the light between the gaps. The combination of webs and gaps acts as an internal thin cladding which supports fewer cladding modes than conventional glass cladding and, significantly, provides increased wavelength spacing between the Bragg resonance and the first cladding mode resonance.
