Latest Patents

One of his latest patents is titled "Photonic Programmable Interconnect Configurations." This patent describes techniques for intra-chip communication within tiled photonic interposers. A photonic interposer may rely on a combination of photonic lanes and electric lanes. For example, a photonic interposer may comprise a photonic integrated circuit (PIC) lithographically patterned with an array of photonic tiles, each photonic tile comprising an on-chip communication unit. The array of photonic tiles is arranged in rows and columns. A plurality of electric lanes places the on-chip communication units of photonic tiles of different rows in electrical communication with one another. A plurality of photonic lanes places the on-chip communication units of photonic tiles of different columns in optical communication with one another.

Another notable patent is "In-network Optical Inference." This innovation provides low-latency machine learning inference by leveraging programmable switches and optical matrix multiplication. IOI uses a transceiver module, called a Neuro Transceiver, with an optical processor to perform linear operations, such as matrix multiplication, in the optical domain. IOI's transceiver modules can be plugged into programmable packet switches, which are programmed to perform non-linear activations in the electronic domain and to respond to inference queries. Processing inference queries at the programmable packet switches inside the network, without sending them to cloud or edge inference servers, significantly reduces end-to-end inference latency experienced by users.
