    摘要: Multiple broad area lasers are coupled to a planar lightwave circuit, where the waveguides come together to form a single wide emitting aperture. A tapered lens is used at the output of the planar lightwave circuit to transform the highly asymmetric mode into a conventional round mode. This configuration allows much higher “brightness”, allowing 10 or more 100 um wide broad area lasers to be coupled into a single 100 um core multimode fiber. This is considerably more efficient than the standard method of combining a single 100 um wide broad area laser to a 100 um core multimode fiber.

    摘要: Described is an optical cross-connect switch having substantially reduced polarization dependent loss in comparison to conventional optical cross-connect switches. The switch includes a first mirror array and a second mirror array defining a first array plane and a second array plane, respectively. The first mirror array reflects an array of optical beams received along a first optical axis to be substantially parallel to a second axis. The first array plane defines a pair of axes orthogonal to each of the first and second optical axes. One of the pair of axes is parallel to the first array plane. The second mirror array is positioned to receive the array of optical beams after reflection from the first mirror array such that the other of the pair of axes is parallel to the second array plane.

    摘要: In embodiments of the present invention, a system and method of cytometry may include presenting a single sperm cell to at least one laser source configured to deliver light to the sperm cell in order to induce bond vibrations in the sperm cell DNA, and detecting the signature of the bond vibrations. The bond vibration signature is used to calculate a DNA content carried by the sperm cell which is used to identify the sperm cell as carrying an X-chromosome or Y-chromosome. Another system and method may include flowing cells past at least one QCL source one-by-one using a fluid handling system, delivering QCL light to a single cell to induce resonant mid-IR absorption by one or more analytes of the cell, and detecting, using a mid-infrared detection facility, the transmitted mid-infrared wavelength light, wherein the transmitted mid-infrared wavelength light is used to identify a cell characteristic.
