    Abstract: An integrated circuit interposer includes a semiconductor substrate layer; a first metal contact layer including a first metal contact section that includes metal contacts arranged for electrically coupling to a first semiconductor die in a controlled collapsed chip connection, and a second metal contact section that includes metal contacts arranged for electrically coupling to a second semiconductor die in a controlled collapsed chip connection. A first patterned layer includes individually photomask patterned metal path sections. A second patterned layer includes individually photomask patterned waveguide sections, including a first waveguide that crosses at least one boundary between individually photomask patterned waveguide sections. A first modulator is coupled to the first waveguide for modulating an optical wave in the first waveguide based on an electrical signal received at a first metal contact in the first metal contact section, and a second modulator is coupled to the first waveguide for modulating the optical wave based on an electrical signal received at a second metal contact in the first metal contact section or the second metal contact section

    Abstract: An apparatus having a segmented optical modulator includes an optical waveguide having three or more segments. Each of three or more optical modulators includes a corresponding waveguide segment and is configured to apply an optical modulation that is proportional to the length of the segment. Three or more electrical contacts receive respective bit values of binary values. Each binary value includes at least three bit values including a least significant bit (LSB) bit value, a most significant bit (MSB) bit value, and at least one intermediate bit (IB) bit value between the LSB bit value and the MSB bit value. At least one waveguide segment of a corresponding optical modulator receiving an LSB bit value is positioned between a first waveguide segment of a corresponding optical modulator receiving an MSB bit value and a second waveguide segment of a corresponding optical modulator receiving an IB bit value.

    Abstract: 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.

    Abstract: Data to be processed includes vector element values of an input vector and matrix element values of a model matrix associated with a neural network model. A vector-matrix multiplication module receives a set of matrix element values for performing a vector-matrix multiplication operation. Processing the data includes computing a plurality of intermediate vectors based on element-wise vector multiplication between different subsets of the vector element values and different respective pre-processing vectors. The vector-matrix multiplication module is loaded with a core matrix, and the input vector is multiplied by the model matrix based on separately multiplying each of the intermediate vectors by the loaded core matrix.
