摘要： A flat substrate bears a set of flat, coplanar diffraction gratings; a jewelry mounting is secured to the substrate. The gratings are arranged to occupy corresponding areas of the substrate that are arranged to correspond to a two-dimensional projection of multiple, non-coplanar facets of a three-dimensional gemstone. Each grating differs from one or more other gratings with respect to grating wavevector direction so that each grating differs from at least one other grating with respect to direction of dispersion of spectrally dispersed output directions of a diffracted portion of light incident on the gratings along a given input direction. The grating wavevectors are spatially distributed among the corresponding gratings to form two or more subsets of three or more gratings along which subsets the corresponding grating wavevector direction of each grating of the subset varies monotonically with position of that grating along a given dimension of the substrate.

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 reconfigurable add-drop multiplexer (R-OADM) comprises an array of channel waveguides coupling two groups of diffractive element sets on a slab waveguide. The channel waveguides include switchable reflectors or are coupled to other channel waveguides by optical switches. Switching a reflector to reflect or setting a switch to couple two waveguides results in a corresponding wavelength channel being added or dropped. Switching the reflector to transmit or setting the switch to uncouple the two waveguides allows the corresponding wavelength channel to pass through the R-OADM without being added or dropped.

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 apparatus comprises a planar optical waveguide having at least two reflectors. The planar optical waveguide substantially confines in at least one transverse spatial dimension optical signals propagating therein, and the reflectors define an optical resonator that supports at least one resonant optical cavity mode. At least one of the reflectors comprises a set of diffractive elements arranged: so that an optical signal in one of the resonant optical cavity modes is successively incident on the diffractive elements; so as to exhibit a positional variation in amplitude, optical separation, or spatial phase; and so as to apply a transfer function to the optical signal successively incident on the diffractive elements. The transfer function is determined at least in part by said positional variation in amplitude, optical separation, or spatial phase exhibited by the diffractive elements.

摘要： An optical apparatus comprises a planar optical waveguide and at least one set of diffractive elements formed in or on the waveguide. The waveguide is arranged to confine propagating optical signals in at least one transverse dimension. The diffractive element set collectively exhibits a positional variation in diffractive amplitude, optical separation, or spatial phase over some portion of the set.

The diffractive element set is collectively arranged so that the input optical signal or the output optical signal is successively incident on the diffractive elements. The diffractive elements are arranged according to an interference pattern derived from computed interference between a simulated design input optical signal and a simulated design output optical signal, the interference pattern exhibiting said positional variation.

摘要： An optical apparatus (spectral filter, temporal encoder, or other) comprises a planar optical waveguide having at least one set of diffractive elements. Each diffractive element set routes by diffraction therefrom a portion of the optical signal propagating in the planar waveguide. The planar waveguide includes at least one material having thermo-optic properties chosen so as to yield a designed temperature dependence of spectral and/or temporal characteristics of the diffracted portion of the optical signal. Variations of material refractive indices, physical dimensions, and/or optical mode distributions with temperature may at least partly compensate one another to yield the designed temperature dependence. Optical materials with ∂n/∂T of various magnitudes and signs may be variously incorporated into the waveguide core and/or cladding. The designed temperature dependence may be: i) substantial temperature independence; ii) a temperature derivative of zero at a selected temperature; or iii) a designed variation with respect to temperature.
