摘要： A monolithically integrated laser which is rapidly tunable over a wide optical frequency range comprises a frequency router formed in a semiconductive wafer defining a tuned cavity. A control circuit applies electrical energy to predetermined controllably transmissive waveguides connecting the frequency routing device with reflective elements defined in the wafer. This tunes the laser to a desired one of a plurality of optical frequencies. Application of such electrical energy creates frequency selective pathways through the wafer able to support selected lasing frequencies. This laser is economical to construct and is useful in high capacity, high speed optical communications networks.

摘要： This invention is directed toward joining an optical fiber to a waveguide on a silicon or silica substrate. In a preferred embodiment, a discontinuity such as a notch is provided in the substrate along each side of a waveguide. The notches, which extend back from the end of each waveguide form air gaps between the ends of adjacent waveguides. Now, when an optical fiber is butt coupled to a waveguide on a substrate with adhesive, the notches at either side of the waveguides prevent adhesive from flowing along the edge of the substrate and onto the end of an adjacent waveguide. In addition, the adhesive flows around and encapsulates the substrate projections defined by the notches along the ends of the waveguide to provide a sturdy butt connection.

摘要： The present invention relates to antennas with a segmented reflecting surface for providing fully or partially overlapping beams from separate feeds associated with each segment without incurring cross-coupling between feeds and power loss. More particularly, a main reflector or a subreflector reflecting surface is segmented to provide separate images of the far field area of the antenna on separate focal surfaces in the vicinity of an original focal surface of a corresponding non-segmented antenna. Feeds disposed at essentially corresponding locations on each of the far field area images produced by each of the segments provide separate beam footprints which overlap each other in the far field area by a predetermined amount.

摘要： The present invention relates to a rectangular corrugated waveguide or feedhorn wherein a plurality of adjacent grooves of a predetermined depth and cross-section are formed, preferably by numerical machining, in a major exposed surface of each of four plates of an electrically conductive material. The four plates are then secured together to form a rectangular corrugated passage therebetween where the ends of the line of grooves in one plate substantially meet and are aligned with the ends of corresponding grooves in another plate to form a solid line of electrically conductive material at the corners of the passage.

摘要： An optical interconnection apparatus including waveguide arrays, such as grating routers and star couplers, has reduced coupling loss by reducing the width of the waveguides in the array, where they connect to the free-space region, so that they are smaller than the gaps between adjacent waveguides. The free-space region is formed by a slab whose thickness is tapered in a transition region, where it connects to the waveguide arrays, so as to essentially eliminate any mismatch loss that would otherwise be caused in an abrupt junction of the waveguide arrays with the free-space region.

摘要： Monitoring of the wavelength and power in an optical network is realized by including a wavelength router in which output ports at particular locations are included to derive samples for the monitoring. A periodic variation in the optical length of the arms of the grating in the router is used to focus additional power at these selected locations. Such a router can also be used for multiplexing and demultiplexing optical signals.

摘要： A method is provided for reducing the polarization shift between different modes of an optical signal propagating in an optical grating having a plurality of waveguides extending in a common plane. The method includes the step of imparting curvature to the optical grating along a line that traverses the plurality of waveguides in a direction that is substantially perpendicular to the direction in which the optical signal propagates. The curvature varies in a nonuniform manner along the line to which it is imparted. The curvature may vary in a substantially linear manner along this line, which in some cases may define a symmetry axis of the grating. Sufficient curvature may be imparted to substantially eliminate the polarization shift. The curvature may be imparted by flexing the optical grating at two contact points respectively located near a longest and shortest of the plurality of waveguides.

摘要： An integrated optic device useful as a planar lens or a low order array multiplexer comprises a pair of optical couplers and an array of plural waveguides extending between the couplers in an "S" configuration to provide closely spaced optical path lengths. An "S" configuration provides equal path lengths for an optical lens. Incremental lengths added to the "S" in the region between curve reversal can provide small path length increments for a low order array multiplexer or demultiplexer.

摘要： A waveguide array comprising a plurality of waveguides which are each outwardly tapered at the aperture of the array in accordance with a predetermined criteria chosen to increase waveguide efficiency. The tapering serves to gradually transform a fundamental Bloch mode, propagating through the waveguide array, into a plane wave in a predetermined direction, and then to launch the plane wave into free space in the predetermined direction. In another embodiment, the waveguides are positioned relative to one another in order to satisfy the predetermined criteria.
