    Abstract: Certain embodiments relate to and involve producing broadband phase-locked frequency combs in the near-infrared and mid-infrared spectral ranges. One such embodiment is directed to a system, with a pump laser and an optical parametric oscillator (OPO) resonator, that is configured to produce broad-bandwidth frequency combs in the near-infrared and mid-infrared frequency ranges. The pump laser is configured to produce femtosecond pulses of light having a pulse repetition rate. The optical parametric oscillator (OPO) resonator that is coupled to the pump laser for facilitating synchronous OPO pumping by matching a roundtrip time of the pulses of light within the OPO resonator with the pulse repetition rate of the pump laser. Among other more specific aspects, the OPO resonator can include a nonlinear optical gain element to provide broad-bandwidth parametric amplification, and optical elements to direct the pulses of light from the femtosecond laser to the nonlinear gain element and to direct subharmonic frequencies of the light out of the optical cavity.

    Abstract: An optical switching system comprising an embodiment with a high pass filter operable to eliminate a portion of frequencies present in an image and an optical device operative to receive the spectrally modified image from the high pass filter, alternatively amplify the spectrally modified image, and propagate at least those frequency components in the spectrally modified image exhibiting a frequency less than an absorption frequency of the optical switching device when the optical switching device is active. Alternatively, the optical switching system may transmit an image only when the system is active. The optical switching system may, for example, comprise superluminescent light emitting diodes which may be, for example, formed in the shape of an inverted truncated prism. For human viewing purposes, the operative transmission ranges may closely coincide with the maximum sensitivity of the photopic response of the corresponding red, blue and green cones in human eyes.

    Abstract: An acousto-optic (AO) frequency shifter includes an anisotropic crystal having an optical axis and an input face, and an acoustic transducer having electrodes affixed to the face for receiving an electrical signal and projecting an acoustic wave into the crystal. The anisotropic crystal is cut relative to the face so that the transducer is at an acoustic angle (θa) corresponding to a predetermined angle of incidence (θi) of an optical beam to be directed relative to the optic axis of the anisotropic crystal to substantially satisfy the parallel tangents phase matching condition.

    Abstract: A system, a structure, and a method for the generation of second harmonic light are provided. A laser system comprises a seed laser that produces a fundamental frequency light, and a nonresonant multiple pass nonlinear structure generates a second harmonic light using the fundamental frequency light. A second harmonic outcoupler outputs the second harmonic light from the laser system and a reflecting structure reflects a remaining portion of the fundamental frequency light back into the nonresonant multiple pass nonlinear structure to generate additional second harmonic light.

    Abstract: A polarization controlling apparatus includes a permanent magnet itself or a permanent magnet to which a part capable of being magnetized is applied, an electromagnet capable of changing the magnitude of a magnetic field to be generated thereby, and a Faraday rotation effect element. The Faraday rotation effect element is disposed at a position at which an interaction magnetic field acts on the Faraday rotation effect element. The interaction magnetic field is produced by an interaction between a magnetic field generated by the permanent magnet and a magnetic field generated by the electromagnet. The Faraday rotation effect element thereby produces a Faraday rotation effect on inputted light. The magnitude of the interaction magnetic field in the Faraday rotation effect element is varied by a magnetic field component generated by the electromagnet to vary the amount of the Faraday rotation effect to be had on the inputted light.

    Abstract: A reduction in size and cost of an optical modulator is achieved with a simple configuration, while improving the modulation characteristics. An optical modulator modulates light branched by an optical coupler and then couples the light via the optical coupler. The optical coupler is formed in a substrate having electro-optic effects. An optical waveguide is formed in the substrate and, includes a turnback section and ends into which the light branched by the optical coupler is input. A signal electrode is provided in the substrate along the optical waveguide. A modulation signal to modulate the light passing through the optical waveguide is input to the signal electrode.
