20150037513 | HIGH RATE DEPOSITION FOR THE FORMATION OF HIGH QUALITY OPTICAL COATINGS - High rate deposition methods comprise depositing a powder coating from a product flow. The product flow results from a chemical reaction within the flow. Some of the powder coatings consolidate under appropriate conditions into an optical coating. The substrate can have a first optical coating onto which the powder coating is placed. The resulting optical coating following consolidation can have a large index-of-refraction difference with the underlying first optical coating, high thickness and index-of-refraction uniformity across the substrate and high thickness and index-of-refraction uniformity between coatings formed on different substrates under equivalent conditions. In some embodiments, the deposition can result in a powder coating of at least about 100 nm in no more than about 30 minutes with a substrate having a surface area of at least about 25 square centimeters. | 02-05-2015 |
20140099117 | 40, 50 AND 100 GB/S OPTICAL TRANSCEIVERS/TRANSPONDERS IN 300PIN AND CFP MSA MODULES - Disclosed by way of exemplary embodiments, a 40/50/100 Gb/s Optical Transceivers/transponders which use opto-electronic components at data rates collectively that are lower than or equal to half the data rate, using two optical duobinary carriers. More specifically, the exemplary embodiments of the disclosed optical transceivers/transponders relate to a 43 Gb/s 300pin MSA and a 43˜56 Gb/s CFP MSA module, both include a two-carrier optical transceiver and the appropriate hardware architecture and MSA standard interfaces. The two-carrier optical transceiver is composed of a pair of 10 Gb/s optical transmitters, each using band-limited duobinary modulation at 20˜28 Gb/s. The wavelength channel spacing can be as little as 19˜25 GHz. The same principle is applied to a 100 Gb/s CFP module, which is composed of four tunable 10 Gb/s optical transmitters, with the channel spacing between optical carriers up to a few nanometers. | 04-10-2014 |
20130243432 | WAVELENGTH ROUTER WITH FEEDBACK CONTROL COMPRISING OPTICAL MONITOR PORTS - An optical waveguide router device with feedback control that uses the fringe frequencies of an optical data signal to derive a wavelength (e.g., temperature) control signal in order to compensate for wavelength variations due to temperature fluctuations and/or other wavelength shifting factors without the need for a reference laser. A monitoring circuit converts an output of at least one output monitoring port to an electrical signal and comparing the output of said at least one output monitoring port against 1) a reference signal, or 2) at least one output from another output monitoring port having a higher or lower frequency fringe of an optical data signal of at least one data port, or 3) at least one output from another output monitoring port having light from diffraction pattern(s), and outputting a control signal reflecting a result of the comparison to control at least one center wavelength of the waveguide router. | 09-19-2013 |

20090087138 | THERMAL CONTROL OF OPTICAL COMPONENTS - A linearized thermal and optical model of an optical integrated circuit can be used to temperature-stabilize one or more optical elements of the circuit using active temperature regulation. To stabilize a single optical element, a temperature sensor and a heater can be provided proximate to the grating. Thermal and optical coefficients can be then used to select an appropriate temperature set-point for the temperature controller that receives readings from the sensor and determines the power dissipated in the heater. Multiple optical elements can be stabilized individually, using the same process and lumping cross-heating factors together with other environmental factors. Alternatively, multiple AWG's can be stabilized using fewer sensors than optical elements, by stabilizing one of the optical elements in the same manner as in the case of a single optical elements, and determining power dissipated in the heaters of the remaining optical elements based on the linearized model. | 04-02-2009 |
