    摘要： The illustrative embodiment of the invention is a surface waveguide having low modal birefringence. The surface waveguide has a composite guiding region that is sandwiched by a lower cladding layer and an upper cladding layer, wherein the cladding layers serve to confine propagating light to the composite guiding region. In accordance with the illustrative embodiment, the composite guiding region is structured so that it exhibits a balanced stress configuration, wherein the stress in the direction that aligns with the TE polarization mode is substantially equal to the stress in the direction that aligns with the TM polarization mode. The balanced stress configuration results in a surface waveguide that exhibits very low modal birefringence.

    摘要： A surface waveguide is disclosed. In the illustrative embodiment, the waveguide has a core and an upper and lower cladding. The core has a thickness that is greater than the critical thickness of the material that composes the core. This is achieved by depositing/growing the core as a conformal layer within a region that is recessed from the planar surface of the lower cladding, wherein the recessed region has a width that is no more than twice the critical thickness of the core material.

    摘要： A method for forming a tapered region in a first layer of a first material is disclosed. The method comprises forming an accelerator layer of a second material on the first layer and forming a mask layer disposed on the accelerator layer. The accelerator layer is exposed to a first etch that removes the second material in a first region and laterally etches the accelerator layer along a second region to expose the first layer in the second region to the first etch. Since the time for which the first layer is exposed to the first etch in the second region is based on the progress of the lateral etch of the accelerator layer, the first etch tapers the first layer in the second region.

    摘要： A sensor for sensing a target chemical with high signal-to-noise ratio is disclosed. In some embodiments, the sensor comprises a sensing region that is optically coupled with an attenuation region. The sensing region receives optical stimulation that comprises light characterized by an excitation wavelength. In response to exposure to the target chemical, the sensing region fluoresces at a fluorescence wavelength. The attenuation region receives light from the fluorescing sensing region that includes light characterized by the fluorescence wavelength (i.e., signal) and light characterized by the excitation wavelength (i.e., noise). The attenuation region conveys the light to a detector that provides an electrical output signal based on the target chemical. While conveying the light, however, the attenuation region improves the signal-to-noise ratio by attenuating light characterized by the excitation wavelength more than light characterized by the fluorescence region.

    摘要： In at least part of the layers of the integrated optical channel waveguide system, such as cladding layers, a passive light guiding layer and an active light guiding layer, an adiabatic layer thickness transition positioned next to a working zone is used to adapt the waveguide structure in the working zones to individually optimized functionality. In this way, the relative layer thickness values as located in the working area, for example a sensor window, a modulation region and a fiber-chip region, can be individually optimized, for example, for maximal evanescent field sensitivity, for minimal modulation voltage and for efficient coupling of light power without the necessity of the optical layer-thickness values elsewhere in the system having to be adjusted. Incorporated in a Mach-Zehnder interferometer this results in an exceptionally sensitive and reliable sensor. Preferably the channel waveguide system is incorporated in an electronic circuitry in which e.g. a phase shift induced by the quantity to be determined is generated.
