摘要： Two grooves 10 are diced in parallel along the light passage direction in a quartz quasi-phase matching element 1. Consequently, as is shown in (b) and (c), a protruding part 11 which is positioned between the two grooves 10 is formed on the upper surface side (in the figures), and a ridge type waveguide 9 is formed inside this protruding part. Accordingly, if light is caused to pass through this ridge type waveguide 9, the light can be caused to pass through the portions with inverted crystal axes (polarization inversion regions) 4, and can be subjected to a wavelength conversion, in a state in which the light is confined into the ridge type wavelength guide 9. As a result, a state can be produced in which the energy of the light is high inside the wavelength conversion region, so that a high wavelength conversion efficiency can be obtained.

摘要： High speed optical modulators can be made of a reverse biased lateral PN diode formed in a silicon rib optical waveguide disposed on a SOI or other silicon based substrate. A PN junction is formed at the boundary of the P and N doped regions. The depletion region at the PN junction overlaps with the center of a guided optical mode propagating through the waveguide. Electrically modulating a reverse biased lateral PN diode causes a phase shift in an optical wave propagating through the waveguide. Prior art forward biased PN and PIN diode modulators have been relatively low speed devices.

摘要： Machining of crystalline lithium niobate is carried out utilizing a laser having a beam with a wavelength near the absorption edge of lithium niobate. The laser beam is provided in pulses of short duration and at a repetition rate selected to ablate the surface of the lithium niobate without damaging the bulk material. Translation of the laser beam and the substrate with respect to each other can be carried out to define a trench of a desired geometry in the lithium niobate.

摘要： In accordance with the invention, a tunable, reconfigurable optical add-drop filter comprises a pair of optical waveguides optically coupled by a microring or microdisk resonator wherein the coupling distance between the resonator and at least one of the waveguides is micromechanically controllable. With this arrangement, the degree of coupling can be tuned after fabrication to provide high level extinction of dropped wavelengths and the filter can be dynamically reconfigured. Advantageously, laser radiation is provided to tune the resonant wavelength.
