摘要： An optical grating comprising a grating layer and two surface layers, the layers being arranged with the grating layer between the surface layers. The grating layer comprises a set of multiple, discrete, elongated first grating regions that comprise a first dielectric material and are arranged with intervening elongated second grating regions. The bulk refractive index of the dielectric material of the first grating regions is larger than the bulk refractive index of the second grating regions. The first surface layer comprises a first impedance matching layer, and the second surface layer comprises either (i) a second impedance matching layer or (ii) a reflective layer. Each said impedance matching layer is arranged to reduce reflection of an optical signal transmitted through the corresponding surface of the grating layer, relative to reflection of the optical signal in the absence of said impedance matching layer.

摘要： A spectral filter comprises a planar optical waveguide having at least one set of diffractive elements. The waveguide confines in one transverse dimension an optical signal propagating in two other dimensions therein. The waveguide supports multiple transverse modes. Each diffractive element set routes, between input and output ports, a diffracted portion of the optical signal propagating in the planar waveguide and diffracted by the diffractive elements. The diffracted portion of the optical signal reaches the output port as a superposition of multiple transverse modes. A multimode optical source may launch the optical signal into the planar waveguide, through the corresponding input optical port, as a superposition of multiple transverse modes. A multimode output waveguide may receive, through the output port, the diffracted portion of the optical signal. Multiple diffractive element sets may route corresponding diffracted portions of optical signal between one or more corresponding input and output ports.

摘要： An optical apparatus comprises at least one primary diffraction grating and at least one reference diffraction grating each formed on or within a common grating substrate. The reference diffraction grating is arranged so as to diffract and disperse spatially according to wavelength a reference optical signal incident on the reference diffraction grating at an input incidence angle.

The reference and primary diffraction gratings exhibit at least one differing grating structural parameter. The reference and primary diffraction gratings are arranged so that a diffracted and spatially dispersed reference optical signal having at least one known wavelength component defines at least one spatial wavelength calibration reference for the diffracted and spatially dispersed input optical signal.

摘要： An optical apparatus comprises an optical interconnect structure defining one or more optical source and receiver ports and one or more interconnect optical signal pathways connecting corresponding optical signal source and receiver ports. The optical interconnect structure comprises an optical waveguide defining a portion of each interconnect optical signal pathway. Each interconnect pathway includes a wavefront diffractive transformation region and a corresponding set of diffractive elements thereof. Each diffractive element set diffractively transforms a corresponding diffracted portion of an incident signal with a corresponding design input signal wavefront into an emergent signal with a corresponding design output signal wavefront. For at least one diffractive element set, only one of the corresponding design input or output signal wavefronts is confined in at least one transverse dimension by the optical waveguide, while the other design wavefront propagates without confinement by the optical waveguide.

摘要： A method comprises computing an interference pattern between a simulated design input optical signal and a simulated design output optical signal, and computationally deriving an arrangement of at least one diffractive element set from the computed interference pattern. The interference pattern is computed in a transmission grating region, with the input and output optical signals each propagating through the transmission grating region as substantially unconfined optical beams. The arrangement of diffractive element set is computationally derived so that when the diffractive element set thus arranged is formed in or on a transmission grating, each diffractive element set would route, between corresponding input and output optical ports, a corresponding diffracted portion of an input optical signal incident on and transmitted by the transmission grating. The method can further comprise forming the set of diffractive elements in or on the transmission grating according to the derived arrangement.

摘要： An optical multiplexing device includes an optical element having at least one set of diffractive elements, and an optical reflector. The reflector routes, between first and second optical ports, that portion of an optical signal transmitted by the diffractive element set. The diffractive element set routes, between first and multiplexing optical ports, a portion of the optical signal that is diffracted by the diffractive element set. More complex optical multiplexing functionality(ies) may be achieved using additional sets of diffractive elements, in a common optical element (and possibly overlaid) or in separate optical elements with multiple reflectors. Separate multiplexing devices may be assembled with coupled ports for forming more complex devices. The respective portions of an optical signal transmitted by and reflected/diffracted from the diffractive element set typically differ spectrally. The portion reflected from the diffractive element set may comprise one or more channels of an optical WDM system.

摘要： An optical apparatus comprises a planar optical waveguide having at least one set of diffractive elements and confining in at least one transverse spatial dimension optical signals propagating therein. Each diffractive element set routes, between corresponding input and output optical ports, a corresponding diffracted portion of an input optical signal propagating in the waveguide that is successively incident on the diffractive elements and is diffracted by the diffractive element set. The optical signals propagate in the waveguide in corresponding diffractive-region optical transverse modes in regions where the diffractive elements are present, and in corresponding non-diffractive-region optical transverse modes in regions where the diffractive elements are absent. The diffractive element set is adapted so as to yield an operationally acceptable level of either or both of i) optical coupling between corresponding diffractive-region and non-diffractive-region optical transverse modes, and ii) diffraction efficiency of the diffractive element set.

摘要： An optical apparatus comprises an optical element having at least one set of diffractive elements and multiple channel optical waveguides. Diffractive elements of each set are distributed among diffractive element subsets corresponding to each of the multiple channel waveguides. Each diffractive element set routes, between a corresponding pair of optical ports, those corresponding portions of an optical signal propagating within the optical element that are received by multiple channel waveguides and back-diffracted within the receiving channel waveguides by corresponding diffractive element subsets. The channel optical waveguides are arranged so that optical signals propagate through regions of the optical element between the ports and the first ends of the channel waveguides. Relative spatial arrangement of the first ends of the channel waveguides and corresponding relative phase shifts imparted in the channel waveguides define at least in part a relative spatial arrangement of the corresponding pair of optical ports.
