摘要： An integrated isolator array is provided having a plurality of waveguides fabricated in a planar optical substrate, each waveguide having input and output sections. An isolator subassembly is received within a transverse trench formed in the substrate between the input and output sections such that it intersects the optical paths of the waveguides. The isolator subassembly, which may consist of layers of Faraday rotator material sandwiched between layers of birefringent crystal material, permits the forward passage of light from the input sections to the output sections of the waveguides while preventing the backward passage of light from the output to the input sections. Each waveguide input section is preferably adapted with a mode-expanding input taper to collimate light propagating through the waveguide. Similarly, each output section is preferably adapted with a mode-reducing output taper to reduce the mode size of forward-traveling light to match that of an output fiber, as well as to collimate light traveling backward within the output section.

摘要： Illumination of the skin by substantial, monochromatic light emitted by LEDs, produces positive therapeutic effects for the treatment of a wide variety of skin conditions. Arrays of LEDs comprising multiple emission colors are preferred light sources for these applications, however, achieving uniform and efficient illumination of a skin target area in close proximity is difficult due to the point-like emission and narrow divergence of lensed LEDs. An illumination apparatus and method, provides a LED system that produces uniform and efficient illumination by combining a well-distributed computed arrangement of each of the LED colors on the array, to enhance the spatial overlap of individual LED outputs across the target area with a diffuse secondary reflector between the LEDs having high reflectivity to further enhance illumination uniformity by allowing light to bounce between LED array panels and the skin.

摘要： An optical assembly, such as a multiple output diode laser pump source for EDFAs, is formed by pressing an optical array emitter chip against a standoff structure protruding from a submount such that the emitter chip deforms to match the curvature of the standoff structure. An IO chip is also juxtaposed against the standoff structure such that its optical receivers can receive optical energy from the emitter chip. The IO chip can provide various optical functions, and then provide an optical array output for coupling into an optical fiber array. The standoff structure preferably contacts the emitter chip over an aggregate contact area much smaller than the area by which the emitter chip overlaps the submount. The materials used for bonding the emitter chip and the IO chip to the submount are disposed in the recesses between standoffs and not on the contact surfaces of the standoff structure.

摘要： An apparatus and method for obtaining Raman spectra that are suitable for continuous real-time monitoring, utilizing the basic technique of Raman spectroscopy in cooperation with wavelength-selective optical amplification are described. The invention improves the detection sensitivity of conventional Raman spectroscopy by orders of magnitude by providing strong wavelength-selective optical amplification and narrowband detection of the intense driving laser and the weak Raman signal(s), thereby essentially eliminating the driving laser signal from the detector and detection electronics. The invention is effective for both Stokes and anti-Stokes Raman lines, and either where the incident laser wavelength is fixed and the Raman spectrum is recorded by analyzing the output of the fiber amplifier with a spectrometer, or where the detection wavelength is fixed and the Raman spectrum is recorded by tuning the wavelength of the laser.

摘要： An integrated optical microstructure includes a substrate carrying an optical waveguide and supporting a medium disposed to receive optical energy from the waveguide. The medium includes an optical re-radiator such as a phosphor, which reradiates optical energy in response to optical energy received from the waveguide. The structure further includes a reflector disposed to redirect some of the input optical energy emanating from the medium back into the medium, to achieve spatial confinement of the input light delivered by the input waveguide. The structure can thereby increase the efficiency of the light conversion processes of re-radiating materials. An aperture in the reflector permits optical energy emitted by the re-radiator to emerge from the structure and to propagate in a preferred direction, such as toward a viewer or sensor. The structure is useful for increasing the brightness of various kinds of small emissive elements which are excited by light delivered from an integrated optical waveguide, including pixels in an information display.
