摘要： A grating-stabilized semiconductor laser comprises a semiconductor laser gain medium, an integrated low-index waveguide, and a waveguide grating segment providing optical feedback for laser oscillation. The laser may be adapted for multi-mode or single-mode operation. A multiple-mode laser may oscillate with reduced power and/or wavelength fluctuations associated with longitudinal mode wavelength shifts, relative to Fabry-Perot lasers lacking gratings. A single-mode laser may include a compensator, wavelength reference, and detector for generating an error signal, and a feedback mechanism for controlling the compensator for maintaining the laser wavelength locked to the reference. The laser may include means for altering, enhancing, tuning, and/or stabilizing the waveguide grating reflectivity spectral profile. The laser may be adapted for optical transverse-coupling to another waveguide.

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.

摘要： An optical apparatus comprises a semiconductor optical device waveguide formed on a semiconductor substrate, and an integrated end-coupled waveguide formed on the semiconductor substrate. The integrated waveguide may comprise materials differing from those of the device waveguide and the substrate. Spatially selective material processing may be employed for first forming the optical device waveguide on the substrate, and for subsequently depositing and forming the integrated end-coupled waveguide on the substrate. Spatially selective material processing enables accurate spatial mode matching and transverse alignment of the waveguides, and multiple device waveguides and corresponding integrated end-coupled waveguides may be fabricated concurrently on a common substrate on a wafer scale. The integrated end-coupled waveguide may be adapted for fulfilling one or more functions, and the device waveguide and/or integrated waveguide and/or spatially selective material processing steps may be adapted in a variety of ways for achieving the needed/desired degree of end-coupling.

摘要： The launch conditions (injected beam size/shape, radial/angular offset from the multimode fiber axis) may be varied to preferentially excite certain transverse modes of multimode optical fiber. To reduce multimode dispersion in the fiber, modes are excited having smaller amplitudes near fiber index defects. Launch conditions may be controlled using a substrate with grooves for launching and receiving fibers, a planar waveguide formed on a substrate along with a groove for aligning the multimode fiber and waveguide, or free-space optical components. A waveguide may provide the desired injected beam size/shape. Spatially selective material processing enables accurate alignment of the groove(s) (and hence the fiber(s) therein), yielding the desired radial/angular offsets. Radial and azimuthal angular offset launch may be employed for constructing an optical mode conditioner, a transmit optical subassembly (TOSA), and other optical devices, assemblies, and subassemblies that launch an optical signal into a multimode optical fiber.

摘要： A photodetector comprises a semiconductor substrate with entrance and reflecting faces formed at the substrate upper surface. The reflecting face forms an acute angle with the substrate surface and is positioned so that an optical beam transmitted through the entrance face into the substrate is internally reflected from the reflecting face toward the substrate upper surface. A photodetector active region is formed on the substrate upper surface and is positioned so that the reflected optical beam impinges on the active region. The photodetector may be mounted on a second substrate for receiving an optical beam from a planar waveguide formed on the second substrate or an optical fiber mounted in a groove on the second 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.
