摘要： An optical waveguide device is provided that can reduce external interference noise. The optical waveguide device includes a substrate, an optical waveguide formed on the substrate, a periodic polarization inversion region formed on the optical waveguide, and an optical thin film formed in a portion of the optical waveguide. The optical waveguide (refractive index: N2) and the optical thin film (refractive index: N1) differ in refractive index dispersion, and the magnitude relationship between the refractive indexes is reversed depending on wavelength. The relationship N1>N2 is established for light having a shorter wavelength, while the relationship N2>N1 is established for light having a longer wavelength.

摘要： A technique for wave-mixing bulk frequency conversion in a network comprising one or more channels is disclosed that enables cost-effective wavelength-conversion. In one particular exemplary embodiment, the technique may be realized by a new class of multi-log wave-mixing-cross-connects that are based on arbitrary b×b space-switching elements, where b>2. In such cross-connects, for any light-path, the worst case number of cascaded frequency-conversions is O(logb(FW)), F being the number of fibers. One benefit of the new design may be maximized when W=O(F), b=O(F), and the worst-case number of cascaded conversions is O(1).

摘要： The present invention aims to simplify a mass production process of an optical waveguide device and to reduce cost as well as noise. The optical waveguide device includes an optical waveguide whose entrance end face and exit end face are substantially parallel to each other. A SHG device is mass-produced by optically polishing an optical material substrate with a large area and then cutting the substrate. This method can mass-produce the optical waveguide devices having a uniform device length. The angle between the exit end face of the optical waveguide and the direction of an optical axis of the optical waveguide at the exit end face is not 90°, thereby reducing return light from the exit end face.

摘要： In a method and apparatus for converting optical wavelength division multiplexed channels to wireless channels, the information carrying optical carriers are first demultiplexed and each optical carrier is then extracted from the data using an optical channelizing technique. The optical frequency of each of the extracted optical carriers is then shifted by an amount equal to the desired wireless carrier frequencies in the broadband wireless channels. Optical heterodyning of the frequency-shifted extracted lightwave carriers with the original data-containing optical signals, which are mutually in phase coherence, in a photodetector results in a set of wireless carriers each modulated with the data carried by the corresponding optical channel.

摘要： Method and apparatus using four wave mixing (FWM) for wavelength conversion. An optical waveguide doped with a rare earth element is pumped so that an input optical signal is amplified as the input optical signal travels through the optical waveguide. The optical waveguide is provided with at least one light which, together with the input optical signal, causes four wave mixing (FWM) to occur in the optical waveguide. The FWM causes a converted optical signal to be produced in the optical waveguide and having a wavelength different from the input optical signal. If the input optical signal is modulated by a transmission signal, then the converted optical signal will also be modulated by the transmission signal. The optical waveguide can be, for example, an erbium doped optical fiber operating as an erbium doped fiber amplifier (EDFA). Therefore, an EDFA can be used for both amplification and wavelength conversion.

摘要： A first control optics assembly receives an incoming optical image. A template optical element produces a template optical intensity profile. A second control optics assembly receives the template optical intensity profile. A polarization separator receives an output from the second control optics. A quarter wave plate changes the polarization of the polarized output therefrom. A combiner receives an output from the first control optics assembly and an output from the quarter wave plate and provides a combined, co-linear propagation output image having an initial beam size. An SLM provides absorption of a portion of the combined output image which changes the local index of refraction of the SLM so that the local reflection at the template optical intensity profile changes. The template optical intensity profile reproduces the image of the absorbed portion as an outgoing image that is reflected back through a portion of the system providing a converted image having substantially the same intensity pattern as the incoming optical image but a different wavelength.

摘要： Electromagnetic radiation is input into a photonic crystal having a shock wave propagating within, wherein interactions between the shock wave and the incident electromagnetic radiation provide for the modification of frequency and bandwidth associated with input electromagnetic radiation. Modifications in frequency of the electromagnetic radiation are on the order of the gap size with 100% efficiency in some cases. Additionally, the bandwidth associated with the electromagnetic radiation is increased or decreased by orders of magnitude based on such interactions. High amplitudes are trapped at the shock front for a controllable period of time, allowing for the controlled manipulation of pulses of light. Lastly, the incorporation of deliberately designed crystal defects and non-linear materials results in the conversion of all the energy in the defect band upwards in frequency if the highest group velocity is less than the shock wave speed.
