摘要： Disclosed is a method of fabricating an optical waveguide device including the steps of forming a mask over a waveguide core material layer so as to leave a portion of the layer exposed, and exposing the structure to an oxidizing environment to form an oxide layer on the waveguide core material layer at least in the exposed portion thereby defining the lateral dimension of the waveguide core. The resulting waveguide core has extremely smooth surfaces for low optical losses.

摘要： A method and apparatus are provided for forming a glass preform which can be directly drawn into a single or multi-mode optical fiber. Single or multi-mode fibers drawn from the preforms described herein have high quality core-clad interfaces since the core and cladding materials are not exposed to crystallization temperatures upon the addition of the core material to cladding material.

摘要： A refractory dielectric body is heated with a plasma torch at conditions which do not result in substantial removal of a surface portion of the body, yet which are sufficient to reduce both surface and bulk impurities. Typically, the body is solid, e.g., a rod as opposed to a tube, and is treated with the plasma in the absence of simultaneous deposition of material onto the body. Advantageously, an isothermal plasma torch is utilized, and the torch advantageously produces an oxygen or oxygen-containing plasma. The invention is useful for reducing chlorine impurities by at least about 30% to a depth of at least about 10 .mu.m, with accompanying reduction of hydroxyl impurities. The invention thus provides a useful method for reducing the concentration of impurities that contribute to imperfections during the process of drawing fiber from an optical fiber preform, without requiring substantial removal of the surface of the preform.

摘要： A thermo-optic device and a method for using it are described. The device has a substrate including a pair of waveguides coupled at first and second coupling regions. At the first coupling region, an input signal is split between the two waveguides. Between the coupling regions on one of the waveguides is a demultiplexer, at least one phase shifting device, and a multiplexer. The signal portions recombine at the second coupling region. Heater strips at the first and second coupling regions alter the temperature at the first and second coupling regions, in response to applied control signals, thereby adjusting the insertion loss and dynamic range of the device. A sensor samples an output signal from the substrate and sends a signal to a controller, which controls the phase shifting devices and the heater strip to maintain the output signal within predetermined signal parameters.
