    摘要: An integrated bi-directional transceiver device for multiple wavelength optical signals that has a high level of wavelength isolation at the receivers of the device and low cross-talk of light between an external laser transmitter and the receivers. A WDM planar light wave circuit (PLC) assembly combines high spatial light confinement waveguide structures and a variable thickness dielectric wavelength selective filter (WSF) on the surface of the device to reflect a first wavelength signal and to pass a second wavelength signal. Embodiments of the invention include branching waveguide structures and folded path waveguide assemblies with multiple WSF's.

    摘要: Waveguide structures in which light confinement strength varies along the direction of light propagation are described. The waveguides include a core adapted to propagate light along a path defined by the core and a cladding material that at least partially surrounds the core. The core and the cladding material each have a refractive index profile in the direction of light propagation. One or more of the profiles or lateral core dimensions are varied along the direction of light propagation, thereby causing the degree of light confinement to vary in the direction of light propagation. With such structures it is possible to tailor the velocity of the light propagating through the core and the confinement of the light to the core for any given core cross section. The structures may be used, for example, in mode-matching an input or output of a waveguide and in fabricating compact directional couplers.

    摘要: Interface loss, diffraction loss, and physical sizes of arrayed-waveguide (AWG) devices, such as AWG routers, are reduced via use of an array of asymmetric waveguide couplers that is inserted between arrayed waveguides. The asymmetric waveguide couplers operate to couple leaked optical power back to the arrayed waveguides. A lenslet matrix may also be used to pre-channel portions of an optical wavefront. The lenslet matrix includes lenslet columns that are aligned with gaps between the arrayed waveguides, such that the portions of the optical wavefront are directed towards the arrayed waveguides rather than towards the gaps.
