Abstract: A solid-state optical amplifier chip is described, with improved pumping, in which pump light from one or more solid-state light sources is coupled efficiently into the doped areas of the chip, resulting in amplification of an optical signal. The optical signal is carried in the core of an optical waveguide. Rare-earth elements are used as dopants, primarily in the cladding of the optical signal's waveguide core, in order to provide amplification of the optical signal through stimulated emission. A variety of waveguide structures are described for routing and distributing the pump light to the doped areas of the chip.

Abstract: A tunable optical device uses a diffraction grating to angularly disperse a collimated beam carrying multiple wavelengths into multiple individually collimated wavelength beams, and then refocuses each of the individual collimated beams to its own focusing point on a moving plate that is located in the region of the focus plane. One or more reflective dots on the moving plate then selectively reflect particular wavelength(s) back to a first output port. The unselected wavelengths are transmitted through the moving plate, where they are then recombined and sent to a second output port. In a typical optical network architecture, the selected wavelength(s) could be viewed as the dropped traffic at a node of the optical network, while the unselected wavelengths could be viewed as the express traffic that is being passed to another node of the network. The device can also be used as a wavelength or beam combiner as well as a splitter.

Abstract: A pin hole or aperture is located or formed adjacent to the end surface of one or more of the input ports or fibers, or adjacent to one or more of the output ports or fibers, of a fiberoptic component. The aperture allows light to enter (or exit) the core of the associated fiber, and the non-transparent layer that surrounds the aperture blocks light from entering or exiting the cladding layer of the associated fiber. This blocking of the evanescent field in the cladding layer serves to reduce the polarization, wavelength, and temperature dependencies of the light coupling to the output port(s) or fiber(s) of the optical component. It can also reduce the passband width of the selected wavelength in tunable optical filter applications. The non-transparent layer surrounding the aperture can be made reflective, and light that is reflected by the non-transparent layer can be used for optical power monitoring.

Abstract: A light source for providing light comprises a light emitting layer and a lens comprising a periodic structure therein that is periodic along at least one direction in a plane. The structure includes or is formed from at least two optically transparent materials of different optical indices. The lens is separated from the light emitting layer, and the radiation propagating from the light emitting layer within an angle to a line normal to the plane will be transmitted by the lens to a far field in an index-guided mode. The separation between the light emitting layer and the lens is such that near field radiation propagating from the light emitting layer towards the lens not within said angle to the line will be scattered and redirected by the first lens to the far field to thereby collimate the radiation propagating from the light emitting layer to the far field.

Abstract: An LED array includes three or more strings of bare LEDs mounted in close proximity to each other on a substrate. The strings of LEDs emit light of one or more wavelengths of blue, indigo and/or violet light, with peak wavelengths that are less than 490 nm. Luminescent materials deposited on each of the LED chips in the array emit light of different wavelength ranges that are of longer wavelengths than and in response to light emissions from the LED chips. A control circuit applies currents to the strings of LEDs, causing the LEDs in the strings to emit light, which causes the luminescent materials to emit light. A user interface enables users to control the currents applied by the control circuit to the strings of LEDs to achieve a Correlated Color Temperature (CCT) value and hue that are desired by users, with CIE chromaticity coordinates that lie on, or near to the black body radiation curve. Preferably a transparent material is dispensed on the substrate between the LED semiconductor chips to substantially surround the LED semiconductor chips. Thereafter at least one layer containing luminescent materials is applied on the LED semiconductor chips and the transparent material.

Abstract: Wavelength-tuning optical filters are presented that also allows for the tuning or real-time adjustment of its bandwidth, or passband width. The bandwidth-adjustable tunable optical filters use one or more diffraction gratings that are fixed in place to provide angular dispersion of different wavelengths. A first rotatable or tilting mirror is used to adjust the angle of incidence of an input optical beam to the diffraction grating or diffraction grating system, while a second rotatable or tilting mirror is used to aim the diffracted optical beam back through the diffraction grating or diffraction grating system, so that a subset of the incoming wavelengths are optically aligned to the end face of an output fiber. The first rotatable or tilting mirror provides tuning or adjustment of the bandwidth or passband width of the tunable optical filter, while the second rotatable or tilting mirror tunes or adjusts the center wavelength of the passband.

Abstract: A Micro-Electro-Mechanical Systems (MEMS) actuator can rotate other, discrete optical elements that may be dimensionally large (especially in terms of thickness), may be of relatively large mass, and may be made of dissimilar materials (i.e., some material other than silicon). The rotating optical element may be reflective or transmissive. The MEMS actuator is used in multiple additional embodiments, allowing the integration of multiple optical functions into a single optical component, for a variety of applications. These optical functions include optical switching, optical attenuation, tunable optical filtering, the adjustment of the phase angle of an optical signal, and the detection or receiving of an optical signal or optical power level.

Abstract: A tunable optical filter integrates the functions of wavelength tuning and power isolation of back reflection. The optical signal enters a Faraday rotator twice, and isolation is provided by two birefringent crystals, having their optical axes oriented at 45 degrees with respect to each other. The two birefringent crystals are on the same side of the Faraday rotator. The integration of an optical tunable filter and an isolator function into a single packaged component helps to reduce the size and complexity of optical amplifier systems, such as EDFAs and PDFAs, operating in the 1550 nm and 1310 nm transmission bands, respectively.

Abstract: An array structure for light emitting diodes (LEDs) uses a patterned metal layer buried beneath LED chips to electrically interconnect non-adjacent chips in series, such that each chip in the LED array can be adjacently surrounded by LED chips of different colors. Thus, when the emission from the LED array is projected to a spot in the far field, its color uniformity over the spot is enhanced. Methods are also described for fabricating the multi-layer circuit board for such an array. Top and bottom patterned metal layers are formed, separated by a patterned insulating layer, so that electrical connections may be made between the metal layers. This provides “vias” between the metal layers for creating “cross-under” electrical connections under the second insulation layer, such that spatially-separated LED chips can be interconnected into strings, while maintaining electrical isolation between LED chips of different colors.
