摘要： An optically switches relatively low power requirements and a relatively broad operating bandwidth. This switch includes a Mach-Zehnder interferometer (MZI) optically coupled at respective ends to an input coupler and an output coupler. One arm of the MZI includes a thermo-optic phase shifter. The output coupler is an adiabatic 3-dB coupler. In one embodiment, the input coupler is a Y-branch coupler having one input port. In a second embodiment, the input coupler is an adiabatic 3-dB coupler having two input ports.

摘要： Disclosed are planar waveguides comprising substantially polarization-independent Bragg gratings. A preferred embodiment of the invention comprises a Si body with a silica lower cladding layer thereon, and a phosphorus P-doped silica core on the lower cladding. Appropriate periodic recessed features are etched into the core, and phophorus P- and B-doped silica upper cladding is deposited over the core. The dopant concentrations are adjusted such that the refractive index difference between core and upper cladding is small (0.35-1.45.times.10.sup.-2), and such that the flow temperature of the upper cladding material is lower than that of the core material. In another preferred embodiment a thin layer of Si.sub.3 N.sub.x (x.about.4) is conformally deposited over the core after the grating etch, and the upper cladding material is deposited onto the Si.sub.3 N.sub.x layer. Bragg devices according to the invention are advantageously used in Integrated Optical Circuits (IOCs), e.g. in IOCs used in WDM optical communication systems.

摘要： A TE-TM polarization manipulating (i.e., splitting, combining or filtering) device is constructed from substrate-supported dielectric thin film waveguides. In a 3-port device, two waveguides have cores of different materials and different effective refractive indices. The waveguide cores overlap in a first transition section and one waveguide core has an adiabatic taper; in this section they also separate adiabatically in and are coupled to a second (e.g., output) section where the waveguides are physically separate and optically decoupled. In a 4-port device, two additional waveguides are coupled in a second adiabatic transition section to the first transition section to enable TE or TM modes to be coupled straight through the device from one input port to a directly opposite output port or to be crossed-over from one input port to a diagonally opposite output port.

摘要： An optical device is disclosed which provides wavelength multiplexing/demultiplexing utilizing a plurality of focusing Bragg reflectors. Each Bragg reflector includes a plurality of confocal (i.e., common foci) elliptical grating lines, with the exit/entrance ports of the input/output waveguides located at the foci of the ellipse. By virtue of the elliptical design, the signal propagating outward from the exit port of the input waveguide will be reflected by the appropriate Bragg reflector and focused into the entrance port of the appropriate output waveguide. When each Bragg reflector exhibits a different ellipticity, but shares one common focal point, optical multiplexing/demultiplexing may be achieved. Optical filtering may be achieved when all Bragg reflectors are designed to have common foci.

摘要： A switching element (e.g., 30) is furnished by an inversion layer (e.g., 55) in a zero resistance state under the influence of a quantizing magnetic field, the inversion layer having a ring geometry. Voltage (e.g., V.sub.o) applied across a pair of localized spaced apart terminals (e.g., 37, 38)--one on a portion of the inner edge of the ring, the other on the outer edge--produces a percolating current in the inversion layer, that is, a current circulating around the ring in a zero resistance state. This percolating current suddenly vanishes when a control voltage is applied to an auxiliary (gate) electrode (e.g., 51), whereby an output voltage (e.g., V.sub.out) previously developed across another pair of localized spaced apart terminals (e.g., 47, 48) on either edge of the ring suddenly also vanishes.

摘要： We describe an interferometric, channel-dropping, optical filter that includes a pair of planar waveguides. The two waveguides are spaced apart by a distance which is periodically varied along the longitudinal axis of the filter in order to effect a periodic optical coupling between them. There are at least three coupling locations, each associated with a coupling constant. The two waveguides have nominally equal effective refractive indices. In preferred embodiments of the invention, the coupling constants decrease symmetrically from the center of the filter toward the ends.
