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： The present invention is a method and apparatus for a rotating, tunable, holographic drop filter connected to a fiber optic source. The filter uses a quasi phase-conjugate optical system for a drop-channel fiber coupling and WDM channels which are introduced to the system. The light from these channels is collimated and passed through a volume phase holographic material so that only one WDM channel is diffracted and the rest pass through the holographic material unaffected. A quasi phase-conjugate diffracted beam is generated by the optical system to reflect the diffracted channel back towards the holographic material. The reflected light is Bragg matched to the holographic material so that it is re-diffracted along a path identical to the original incident light beam. A free-space circulator may be used to direct the diffracted beam to a fiber optic collimator, which is different from the fiber optic collimator of the incident light beam.

摘要： The invention combines fluorescent QDs and methods to dispense and detect them efficiently in a compact volume for a range of optical tagging applications. Micro-fluidic devices are used for mixing water-soluble fluorescent QDs in aqueous solutions to create a multi color fluorescent nano-optical tag, and gratings are used for spreading the spectral components of the fluorescent signal leading to an improvement in optical data storage capacity over prior art methods. The spectral signature of the tag is detected by a compact read-out head with a grating spectrometer. One way is to dispense the tag within the pits of a DVD or CD using an ink-jet nozzle and exciting them by a large range of wavelengths each shorter that the emission peak. The filters have a high immunity to prolonged exposure to high temperatures, and up to 41 infrared filters can be holographically recorded by spatial multiplexing of the substrate.
