Inventors:

Jie LIN - San Francisco CA, US

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

A mobile device (or app on the mobile device) can be paired with an application executing on a computing device external to the mobile device. The pairing can be based at least in part upon a unique ID assigned to the application on the computing device by a network server. For example, the network server can assign the application on the computing device a unique ID and the application can provide a machine-readable code corresponding to the unique ID. The (app on the) mobile device can read/scan the machine-readable code to become paired with the application. Subsequent to the pairing, (the app on) the mobile device and (the application on) the external computing device can interact dynamically via a network (e.g., communicate in real-time via the Internet). In some embodiments, the network server can facilitate the dynamic interaction between the mobile device and the external computing device via the network.

International Classification:

G02B 6/12

G02B 6/136

Abstract:

A method for making a multimode interference (MMI) coupler with an arbitrary desired splitting ratio includes forming a thin-film of silicon-nitride material overlying a SOI substrate. The method further includes obtaining geometric parameters of a standard MIMI coupler including a rectangular MMI block and one input port and two output ports in taper shape with one of standard splitting ratios under self-imaging principle which is close to the desired splitting ratio. Additionally, the method includes tunning the input port to an off-center position at front edge of the MMI block. The method further includes making a first output port to a first off-center position flushing with a side edge of the MMI block, adjusting a second output port to a second off-center position. The method includes tunning the MMI block to obtain optimized geometric parameters for approaching the selected arbitrary splitting ratio, and etching the thin-film of silicon-nitride material.

Abstract:

An optical splitter includes a silicon-on-insulator substrate having a cladding layer. The optical splitter also includes a first waveguide of a first width and a first length buried in the cladding layer and a second waveguide of a second width and a second length buried in the cladding layer disposed in close proximity of the first waveguide by a gap distance. A ratio of the second width over the first width is configured to be smaller than 1 while the first length, the second length, and the gap distance are configured to allow evanescent coupling of a first confined mode of an optical signal in the first waveguide into the second waveguide with a certain splitting ratio being achieved in a range of 1% to

International Classification:

G02B 27/28

Abstract:

The present application discloses a polarization beam splitter (PBS). The PBS includes a silicon substrate and a planar structure formed thereon characterized by an isosceles trapezoid shape with a first parallel side and a second parallel side connected by two tapered sides. The first parallel side has longer width than the second parallel side, both of which is separated by a length no greater than 100 μm along a line of symmetry bisecting the pair of parallel sides. The PBS further includes a pair of input ports coupled to the first parallel side and a pair of output ports coupled to the second parallel side. The planar structure is configured to receive an input light wave of any wavelength in C-band via one input port and split to a TE-mode light wave and a TM-mode light wave respectively outputting to the pair of output ports.

Abstract:

Methods, apparatuses, and systems for determining a binary mask pattern from a pixelated mask pattern include: determining, by a processor, based on a fast marching method (FMM), arrival values for pixels of a portion of the pixelated mask pattern; determining the binary mask pattern based on the arrival values; and updating at least one of the arrival values based on a comparison between a design pattern corresponding to the pixelated mask pattern and a substrate pattern simulated based on the binary mask pattern.

International Classification:

G02B 6/293
G02B 6/12

Abstract:

A multiplexer/demultiplexer for at least two wavelengths in O-band. The multiplexer/demultiplexer includes a silicon waveguide block having a first port, a second/third port respectively in bar/cross position at an opposing end plane relative to the first port. The silicon waveguide block is configured to provide a general interference excitation of a light wave of a first wavelength and a second wavelength respectively selected from two windows in O-band. The light wave is either inputted via the first port and split into a first output light of the first wavelength out of the second port and a second output light of the second wavelength out of the third port, or is combined of a first input light of the first wavelength from the second port and a second input light of the second wavelength from the third port and outputted via the first port with both wavelengths.

International Classification:

G02B 6/27

Abstract:

A waveguide-based polarization splitter-rotator (PSR) includes a converter with tapered rib-structure configured to convert TM0/TE0 polarization mode of an input light to a TE1/TE0 mode, a splitter coupled to the first plane for splitting the input light evenly to a first wave at a first port and a second wave at a second port. Furthermore, the PSR includes a phase shifter having a first arm coupled to first port and a second arm coupled to the second port. The first arm guides the first wave to a third port with no phase shift while the second arm adds 90 or 270 degrees to the second wave. The PSR also includes a 2×2 MMI coupler for coupling the first wave and the second wave to output a first output light in TE0 mode exclusively from TM0 mode and a second output light in TE0 mode exclusively from TE0 mode.
