| 20110142396 | ATHERMAL SILICON PHOTONICS ARRAY WAVEGUIDE GRATING (AWG) EMPLOYING DIFFERENT CORE GEOMETRIES IN THE ARRAY WAVEGUIDES - A silicon photonics array waveguide grating (AWG), and methods of their manufacture, including a plurality of silicon photonics array waveguides running from at least one of an input and output slab waveguide region, wherein first sections of each of the plurality of array waveguides have a first core geometry; and second sections of each of the plurality of array waveguides have a second core geometry. The first and second core geometries may comprise different waveguide core widths, and/or different core structures. AWG temperature stability is provided by the techniques of the present invention. | 06-16-2011 |
| 20100272394 | ARRAYED WAVEGUIDE GRATING (AWG) WITH DIFFERENT RADII IN THE INPUT AND OUTPUT SLAB REGIONS - Arrayed waveguide grating (AWG) circuits are disclosed, having different radii in the slab regions to supplement and/or replace other mechanical techniques which enable athermal AWGs. Dual band, interleaved pairs of athermal AWGs are also disclosed, with improved cost, space and center wavelength properties, for, e.g., optical line terminal (OLT), and remote node (RN) applications. | 10-28-2010 |
| 20100245831 | PLANAR LIGHTWAVE FOURIER-TRANSFORM SPECTROMETER - A transform spectrometer implemented on a planar waveguide circuit (PLC), having an input optical signal waveguide carrying an input optical signal to be analyzed; a plurality of couplers, each connected to the input optical signal waveguide, and each including a coupler output for carrying a coupled optical signal related to the input optical signal. An array of interleaved, asymmetrical waveguide Mach-Zehnder interferometers (MZI) is formed on the PLC, each having at least one input MZI waveguide, each MZI input waveguide receiving a coupled optical signal from a respective coupler output; wherein at least some of the input MZI waveguides intersect in a common layer of the PLC, at an angle which allows their respective coupled optical signals to transmit without unacceptable attenuation. This arrangement improves spatial efficiency of the PLC, allowing more MZIs to be implemented, resulting in increased spectral resolution. | 09-30-2010 |
| 20100111478 | NON-LINEAR FIBER ARRAY HAVING OPPOSING V-GROOVE STRUCTURES - A fiber array unit (FAU) having plurality of optical transmission channels (e.g., fiber optics) terminating at a side surface thereof for carrying optical signals to and/or from waveguides in a planar lightwave circuit (PLC). The optical transmission channels of the FAU terminate at the side surface thereof in a non-linear, cross-sectional pattern (e.g., a curved pattern). The non-linear pattern is determined by a pattern of grooves formed in a substrate of the FAU, in combination with a lid which may also have an inverse, non-linear pattern, to thereby rigidly, reliably and permanently hold the optical transmission channels in place. | 05-06-2010 |
| 20090016716 | FIBER ARRAY UNIT WITH INTEGRATED OPTICAL POWER MONITOR - A technique for monitoring optical power in a fiber array unit having a plurality of optical transmission waveguides terminating at an edge thereof for carrying optical signals to and/or from a PLC. A tapping filter is placed within a slit formed in the substrate and interrupting the transmission channels, thereby tapping at least some of the optical power from the channels and directing the tapped optical power toward respective photodetector channels for detection, while allowing other optical power to continue transmission in the at least one channel of the fiber array unit. | 01-15-2009 |
