    摘要： The invention relates to a tunable optical add/drop module (TOADM) monolithically integrated on a single planar lightwave circuit (PLC). The present invention overcomes the shortcomings of the prior art by providing virtual pupils at the interface between the channel waveguides and the slab waveguide on the PLC for focusing each wavelength channel, and additional on-chip lenses on the PLC for transforming the focal plane of the spatially dispersive demultiplexer into a substantially flat plane at the edge of the PLC. On-chip lenses are realized as reflective surfaces within slab waveguiding regions having a surface curvature to provide optical power.

    摘要： The present invention extends the concept of a standard array waveguide grating (AWG), which focuses each wavelength component launched via an input AWG to a Rowland circle inside a planar lightwave chip (PLC) where discrete waveguides are located, to one which focuses each wavelength component outside of the PLC chip along a straight line. An array of MEMS mirrors or other redirecting elements is positioned at the focus location for independently redirecting each of the wavelength channels back to any number of selected output AWGs formed on the same PLC chip as the input AWG.

    摘要： In selected embodiments, improved image restoration is realized using extensions of Wiener filtering combined with multiple image captures acquired after simple, fast reconfigurations of an optical imaging system. These reconfigurations yield unique (distinct) OTF responses for each capture. The optical imaging system may reduce fabrication cost, power consumption, and/or system weight/volume by correcting significant optical aberrations. The system may be configured to perform independent correction of fields within the total field of regard. The system may also be configured to perform independent correction of different spectral bands.

    摘要： A wavelength cross connect is provided in which there is a dispersive arrangement per port for each input port and each output port. Some of the dispersive arrangements have differing characteristics so as to result in different performances at the ports. The dispersive arrangements can differ in the selection of different dispersive elements or differing coupling optics. A particular implementation features a first set of waveguide dispersive elements having first performance characteristics, and a second set of waveguide dispersive elements having second performance characteristics.

    摘要： Selected embodiments use a relatively small image detector and a scanning mirror to obtain effective performance of a larger image detector. An imager with folded optics captures images of different field positions of a field of view (FOV), and stitches the images together for a larger image of the FOV. The stitched image is processed to identify portions of interest within the larger image, for example, using a cuing algorithm. The portions of interest are scanned again to capture enhanced quality images using, for example, longer dwell time for enhanced contrast. Another image of the FOV or a part of the FOV is stitched together using the enhanced quality images.

    摘要： A scanning optical spectrometer with a detector array is disclosed, in which position of focused spot of light at the input of a dispersive element such as arrayed waveguide grating (AWG) with a slab input, is scanned using a micro-electro-mechanical (MEMS) tiltable micromirror so as to make the dispersed spectrum of light scan over the detector array coupled to the AWG. Sub-spectra recorded using individual detectors are concatenated by a processor unit to obtain the spectrum of input light.

    摘要： Illumination for the platen of a finger receiving imaging prism is provided from a source mounted below the prism and reflected to the platen surface at an angle greater than the critical angle, through a beam folding input prism that is positioned primarily below and behind a front edge of the platen. Transmitting and scanning optics of the system are positioned behind and below the imaging prism, and an output prism is bonded to the imaging prism to receive light reflected from the platen, to shift the path of this reflected light downwardly and to direct it rearwardly toward system optics. The beam from the output prism is fed through an F-Theta scanning lens to a scanning mirror mounted on a scanning galvanometer that causes the fingerprint image to precisely scan across a linear array of print camera sensors that are repetitively sampled to provide a readout of the entire surface of the prism platen for reading a slap print. For a roll print, a portion of the beam is sent to a linear array of sensors of a roll camera to provide an estimate of position of the line of contact of the finger during its rolling motion over the platen. The estimate controls the galvanometer and scan mirror to align the image of the line of contact of the rolling finger precisely with the linear array of the print camera sensors.
