摘要： A method of and/or device for writing to an optical modulator using electromagnetic write beams, the modulator having a photorefractive converter body in which the space-modulated write beam may induce changes in the refractive index. An external voltage may be applied to the converter body. The intensity of the external voltage may be selected within a voltage range in which the buildup of changes in the refractive index may be accelerated by an increase in the charge carrier mobility or charge carrier density.

摘要： A method for processing received electromagnetic radiation includes receiving electromagnetic radiation having a plurality of carrier waves in the frequency range between 0.1 and 10 terahertz and having modulated onto the carrier waves information with a signal frequency of less than 50 GHz. The received radiation is filtered with a filter that is tunable in the frequency range from 0.1 to 10 terahertz so as to obtain at least one carrier wave as a terahertz signal. The terahertz signal is provided to a detection circuit that is sensitive to the terahertz signal frequency.

摘要： In the present invention, a volume holographic optical element is used as a pump coupler. The holographic coupler allows at least one pump wavelength to be coupled into the laser medium. The direction of the pump beam onto the coupler is not co-linear with the direction of the signal beam out of the coupler. The invention further provides the coupling of more than one pump wavelengths using a single holographic coupler element while maintaining the high isolation between pump and signal beam. The invention further provides a narrow-band reflection grating of various efficiencies for the signal beam (as part of the laser cavity).

摘要： The present invention provides a multi-channel turnable filter and methods for making such a filter. In one embodiment, the filter comprises a bank of gratings imprinted into a filter material, such as Lithium Niobate. In another embodiment, the filter comprises a bank of gratings imprinted on a thin-film filter. An optical read-head comprising a pair of lenses is configured to pass light from within an optical fiber carrying multiple wavelengths through an appropriate grating to extract or drop a specific wavelength. To ensure continuous data transmission, the filter is tuned to a wavelength by configuring the read-head to move in a hitless manner. In one embodiment, the gratings are recorded by the interference of two beams. A first plane wave reflects off a first mirror stack and a second plane wave reflects off a second mirror stack In another embodiment, the gratings are recorded by a phase masking method.

摘要： Method for preparing a purified crystal for use in an optical component, from an impure crystal having impurities or crystal defects capable of causing a specific absorption of incident light, includes heating the impure crystal to a temperature at which ions in the crystal are mobile and provide conductivity. A part of the crystal is illuminated with an electromagnetic purifying beam having a frequency in or near a visible frequency range so as to optically excite and migrate charges in the crystal, the charges being compensated by a counter-migration of the ions so as to be fixed in place thereafter so as to provide a purified crystal zone. The crystal is cooled to a future operating temperature.
