Abstract: 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.

Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication. A computer system comprises: a plurality of memory aggregation devices configured to retrieve data from and store data in a plurality of random access memory modules forming a unified contiguous memory address space disaggregated from a processing unit; a plurality of computational devices configured for simultaneously launching a plurality of data signals including memory read and/or write requests for the data to the plurality of memory aggregation devices; and a plurality of communication links coupling each of the plurality of memory aggregation devices to each of the plurality of computational devices for transferring the data therebetween.
