摘要： The invention provides integrated optical matching elements for use in integrated optical devices. The matching elements each comprise one or more lenses. The lenses may have low index contrast with the surrounding medium. Required dioptric power is achieved by using a train of lenses. Optical matching elements according to the invention can be used to enhance the optical coupling between channel waveguides and slab waveguides. The insertion loss of devices such as optical power splitters, optical couplers and arrayed waveguide grating routers can be reduced by incorporating optical matching elements according to the invention.

摘要： The present invention provides an arrayed waveguide such that each waveguide of the grating has a substantially uniform width, but the width of any single waveguide in the grating is selected based on a predetermined birefringence required for the waveguide. Generally, the narrowest grating waveguide has the longest overall length and the widest grating waveguide has the shortest overall length. The remaining intermediate waveguides have widths that are interpolated between the narrowest and widest waveguide gratings. With an appropriate width for each waveguide, an arrayed waveguide grating is provided that has low polarization dependent wavelength.

摘要： An optical integrated circuit (OIC) or optical apparatus upon which a waveguide-grating router (WGR) device is fashioned is provided, where the circuit is configured to optimize a passband for each channel transmitted on an output waveguide. The WGR has two or more waveguides of varying widths optically coupled to a slab waveguide. The widths can be configured to facilitate producing a substantially uniform frequency-limited bandwidth, a substantially uniform wavelength-limited bandwidth, a substantially uniform isolation value, and/or a substantially uniform value for insertion loss between the output waveguides, which in turn facilitates producing optical data communication devices with more consistent transmission parameters and higher quality. In addition to various widths, the shape of the delivering end of a slab waveguide can be fashioned to further improve the consistency and quality of such parameters.

摘要： An optical apparatus and method establishes a value of group velocity dispersion in wavelength division multiplexing applications. The optical apparatus includes at least one input waveguide, a first slab waveguide, an arrayed waveguide grating, a second slab waveguide, at least one output waveguide, and at least one transition segment optically connecting the at least one input waveguide to the first slab waveguide. The transition segment features a taper and an extension. The wide end of the taper is optically connected to the first end of the extension and the second end of the extension is optically connected to the slab waveguide and the first and second ends are equal in width. The extension may have a constant or non-constant width and may include a heating element. When a plurality of transition segments are featured, each transition segment may have similar or different properties. The transition segments may be used at the output side of the optical apparatus as well as at the input side.

摘要： Optical networks can comprise a branch structure with the de-multiplexing/multiplexing structure that operates to disperse a plurality of optical bands. Thus, the optical network comprises an optical network connection with a common optical channel, a plurality of de-multiplexed branch optical service connections and the de-multiplexing/multiplexing structure. In some embodiments, one optical band can be used to deliver input from a common channel to the branch node and the other optical band can carry output along the common channel from the branch node. The de-multiplexing/multiplexing element can be an arrayed waveguide grating. The AWG can have desirable architecture to efficiently provide the corresponding functions with respect to the two optical bands. Appropriate photodetectors and light sources can be associated with the AWG.
