    摘要： Apparatus and method for increasing the concentration of a chemical substance in a fluid comprise a micro-fluidic elongated channel formed in a substrate, with the channel being in fluid-flow communication with an ambient region along its elongated dimension. In general, the fluid includes first and second chemical substances having different vapor pressures. The apparatus includes an evaporation controller for increasing the evaporation rate of the fluid from the channel into the ambient region, thereby increasing the concentration of the lower vapor pressure (LVP) substance in the portion of the fluid remaining in the channel and increasing the concentration of the higher vapor pressure (HVP) substance in the portion of the fluid evaporated into the ambient region.

    摘要： A self-orienting optical component advantageous for assembling sub-optical assemblies in which the components must be precisely aligned comprises a component having a magnetic film deposited on a portion of its outer surface so that a magnetic field applied adjacent the optical component will induce the optical component to move to a pre-determined orientation. Advantageously, the optical component also has further layers deposited on portions of its outer surface for aiding in adhesion, soldering, or light transmission. An improved method of assembling an optical subassembly comprises depositing a film of magnetic material over a portion of the outer surface of the optical component and applying a magnetic field to the optical component to induce it to move to a pre-determined orientation to aid in positioning it on a submount.

    摘要： An apparatus for stabilizing the wavelength of light emitted by a laser or light source comprising a divider for dividing a sample of emitted light into a first and second portion; a first photodetector configured to measure an intensity of the first portion and a second photodetector configured to measure an intensity of the second portion, the second photodetector configured to receive the emitted light via an optical frequency discriminator, such as a dielectric coating, wherein the optical frequency discriminator is configured to modify the intensity of the emitted light at the second photodetector as a function of an optical frequency of the emitted light; and a processor configured to maintain a desired level corresponding to a ratio of the intensity measured by the first photodetector and the intensity measured by the second photodetector, so as to provide a feedback control signal to adjust the wavelength of the emitted light. In one embodiment, the first and second photodetectors are photodetector diodes having a base electrode, a first electrode and a second electrode. The diode is configured to generate an electrical current between the base electrode and the first electrode corresponding to the intensity of light received by the first photodetector and to generate an electrical current between the base electrode and the second electrode corresponding to the intensity of light received by the second photodetector. In still another embodiment, the sample is a back-facet emission emitted by the source, wherein the entire apparatus is disposed on a silicon chip having the frequency discriminating dielectric coating applied directly to its surface.

    摘要： The specification describes thermo-optically controlled waveguides where the thermo-optic control is a heater strip precisely aligned to the waveguide core by using the heater strip as an etch mask to define at least part of the core/upper cladding structure. In one embodiment the heater strip mask is larger than the underlying waveguide core so as to produce, on etching, a core surrounded with a minimum of cladding material on the sidewalls of the core, and a confined heat channel between the waveguide core and the heater strip. In a second embodiment the heater strip is used as an etch mask to define a core cladding stack, and a third cladding layer is deposited to clad the sidewalls of the core. In this embodiment, the cladding material in the stack can be optimized for thermal conductivity, and the third cladding material can be optimized for thermo-optic sensitivity.
