Abstract: An optical apparatus comprises a set of diffractive elements on a substrate. They are arranged: (i) to receive an input signal propagating from an input port as a diffraction-guided optical beam, (ii) to diffract a portion of the received input signal as an output signal, (iii) to route the output signal to propagate to an output port as a diffraction-guided optical beam, and (iv) to exhibit a positional variation in diffractive amplitude, optical separation, or spatial phase over some portion of the set. The arrangement of the diffractive elements corresponds to an interference pattern derived from computed interference at a surface of the substrate between a simulated design input and output optical signals. Each diffractive element comprises at least one trench segment positioned along a path defined by a constant-phase contour of the interference pattern. Each trench segment is substantially rectangular or trapezoidal in transverse cross section.

Abstract: 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.

Abstract: 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.

Abstract: A planar optical waveguide has a set of diffractive elements and confines propagating optical signals in at least one transverse spatial dimension. Each diffractive element set routes, between input and output ports, a corresponding diffracted portion of an input optical signal propagating in the planar optical waveguide that is diffracted by the diffractive element set. The input optical signal is successively incident on the diffractive elements. A desired level of birefringence for a chosen signal optical transverse mode is determined at least in part by i) selected areal density of diffractive elements, ii) selected diffractive element height and position along the confined transverse spatial dimension, iii) selected thicknesses and indices of materials comprising the diffractive elements, or iv) selected thicknesses and stress-optical coefficients of materials comprising the planar optical waveguide, and selected thermal expansion coefficient differentials among materials comprising the planar optical waveguide or comprising a waveguide substrate thereof.

Abstract: A slab optical waveguide confines in one transverse dimension optical signals propagating in two dimensions therein, and has a set of diffractive elements collectively arranged so as to exhibit positional variation in amplitude, optical separation, or spatial phase. The diffractive elements are collectively arranged so as to apply a transfer function to an input optical signal to produce an output optical signal. The transfer function is determined at least in part by said positional variation in amplitude, optical separation, or spatial phase. The waveguide and diffractive elements are arranged so as to confine only one of the input and output optical signals to propagate in the waveguide so that the optical signal thus confined is successively incident on the diffractive elements, while the other optical signal propagates unconfined by the waveguide in a direction having a substantial component along the confined dimension of the waveguide.
