摘要： An optical phase-shifting device includes a ribbed waveguide portion on an insulating layer, the waveguide portion having a p-n or p-i-n junction extending in a longitudinal direction and having a height. A pair of slab portions are disposed adjacent the waveguide portion, one on each side of the ribbed waveguide portion and on the insulation layer. The slab portion have higher doping concentrations than the respective doping concentrations in the ribbed waveguide portion. At least a portion of each slab portion has a height increasing with distance from the waveguide portion, with the slab height being smaller than that of the waveguide portion at the junction between the waveguide portion and slab portion. A pair of contact portions are formed adjacent the respective slab portion and further away from the waveguide portion. A portion of each contact portion can also have a height varying with distance from the waveguide portion.

摘要： A significant challenge occurs when two Mach-Zehnder optical modulators are placed in close proximity next to one another, resulting in substantial cross talk. An optical modulator configured to reduce crosstalk between adjacent optical modulators includes a positive polarity signal electrode electrically coupled between a driver and an optical phase shifting section, and a negative polarity signal electrode electrically. The positive polarity signal electrode comprises a first positive polarity signal electrode section extending adjacent to a first optical waveguide path, and a second positive polarity signal electrode section extending adjacent to a second optical waveguide path. The negative polarity signal electrode comprises a first negative polarity signal electrode section extending adjacent to the second optical waveguide path and the first positive polarity signal electrode section, and a second negative polarity signal electrode section extending adjacent to the first optical waveguide path and the second positive polarity electrode section.

摘要： Systems and methods that include: providing input information in an electronic format; converting at least a part of the electronic input information into an optical input vector; optically transforming the optical input vector into an optical output vector based on an optical matrix multiplication; converting the optical output vector into an electronic format; and electronically applying a non-linear transformation to the electronically converted optical output vector to provide output information in an electronic format.
In some examples, a set of multiple input values are encoded on respective optical signals carried by optical waveguides. For each of at least two subsets of one or more optical signals, a corresponding set of one or more copying modules splits the subset of one or more optical signals into two or more copies of the optical signals. For each of at least two copies of a first subset of one or more optical signals, a corresponding multiplication module multiplies the one or more optical signals of the first subset by one or more matrix element values using optical amplitude modulation. For results of two or more of the multiplication modules, a summation module produces an electrical signal that represents a sum of the results of the two or more of the multiplication modules.
