Matrix Multiplication Using Mode-Division Multiplexing and Coherent Detection (Topic B.2.2 Optoelectronics)
Abstract
The objective of this research program is to perform a proof-of-concept demonstration for a new paradigm for optical matrix-vector multiplications. When performed in the electrical domain, matrix-vector multiplications are decomposed into multiply-accumulate (MAC) operations. In the new paradigm proposed here, multiplications are performed through coherent mixing, and accumulation is performed in the spatial domain using mode-division multiplexing. Therefore, our MAC operations are passive, consume only power associated with data modulation. Combined with wavelength-division multiplexing and 3-dimensional spatial parallelization, this concept can be extended to batch matrix-matrix multiplication, which is a foundational operation in artificial neural networks.
