摘要： An optical apparatus comprises an optical device fabricated on a substrate, an external-transfer optical waveguide fabricated on the substrate and/or on the optical device, and a transmission optical waveguide. The optical device and/or the external-transfer waveguide are adapted for and positioned for transfer of optical power therebetween (end-transfer or transverse-transfer). The external-transfer waveguide and/or the transmission waveguide are adapted for transverse-transfer of optical power therebetween (mode-interference-coupled or adiabatic). The transmission waveguide is initially provided as a component mechanically separate from the substrate, device, and external-transfer waveguide. Assembly of the transmission waveguide with the substrate, device, and/or external-transfer waveguide results in relative positioning of the external-transfer waveguide and the transmission waveguide for enabling transverse-transfer of optical power therebetween. Optical power transfer between the device and the transmission waveguide through the external-transfer waveguide is thereby enabled. The transmission waveguide may preferably comprise a planar waveguide on a waveguide substrate.

摘要： A fiber-optic-taper loop probe includes first and second fiber segments, first and second tapering segments, and a center taper segment. In a preferred embodiment, first and second fiber segments are about 125 μm in diameter, and the center taper segment has a substantially constant diameter of about 2-5 μm. The fiber-optic taper forms a loop, the center taper segment remaining substantially straight and opposite the crossing point of the loop. The loop is secured to a support structure to maintain its shape and facilitate positioning relative to an optical component to be tested. The fiber segments may be connected to an optical characterization system including one or more light sources, lasers, detectors, spectrometers, etc. The geometry of the loop enables transverse-optical-coupling of the loop probe with an optical component without undesirable contact between other portions of the loop probe and other portions of the optical component and/or substrate.

摘要： A multiple-core optical waveguide comprises: a substrate; lower and upper waveguide core layers; a waveguide core between the upper and lower waveguide core layers; upper and lower cladding; and middle cladding between the upper and lower waveguide core layers substantially surrounding the waveguide core. Each of the lower, middle, and upper claddings has a refractive index less than refractive indices of the lower waveguide core layer, the upper waveguide core layer, and the waveguide core. Along at least a given portion of the optical waveguide, the upper and lower waveguide core layers extend bilaterally substantially beyond the lateral extent of a propagating optical mode supported by the optical waveguide, the lateral extent of the supported optical mode being determined at least in part by the width of the waveguide core along the given portion of the optical waveguide.

摘要： An optical apparatus comprises: a semiconductor substrate; a semiconductor optical device integrally formed on the substrate and having a device end face; and a low-index planar optical waveguide integrally formed on the semiconductor substrate at the device end face. The waveguide is end-coupled at its proximal end to the optical device through the device end face and is arranged so as to comprise a waveguide mode converter. The waveguide is arranged at its distal end to transmit or receive an optical signal through its distal end to or from another low-index optical waveguide end-coupled with the integrally-formed waveguide and assembled with the integrally-formed waveguide, optical device, or substrate. The optical apparatus can further comprise a discrete low-index optical waveguide assembled with the integrally-formed waveguide, optical device, or substrate so as to be end-coupled with the integrally-formed waveguide at its distal end.

摘要： An optical apparatus is made by mounting segments of a GRIN optical medium on a substrate in at least one groove thereon. The GRIN segments are longitudinally spaced apart from one another on the substrate, and are arranged so that a free-space optical beam received through the distal end face of the first GRIN segment is transmitted through the proximal end face of the first GRIN segment, propagates to the proximal end face of the second GRIN segment, is received through the proximal end face of the second GRIN segment, and is transmitted as a free-space optical beam through the distal end face of the second GRIN segment. The GRIN segments can be formed by division of a single GRIN optical medium mounted on the substrate.

摘要： An optical component may comprise a horizontal member with two side walls and a substantially transparent end wall protruding from the horizontal member. The end wall, side walls and horizontal member may partially enclose an interior volume, and optical functionality is imparted in any suitable manner on at least a portion of the end wall. An optical assembly may comprise such an optical component mounted on a waveguide substrate along with a planar waveguide and a second waveguide, which are end-coupled by either reflection from the optical component end wall or transmission through the optical component end wall. An end portion of a planar waveguide may be received within the interior volume of the mounted component. Proper positioning of the optical component relative to the waveguides may be facilitated by alignment surfaces and/or alignment marks on the component and/or waveguide substrate.
