Title:

Nanophotonics technology toward optical logic circuits

Abstract:

On-chip photonic systems are expected to lead to a paradigm shift in networks on a chip. They can minimize energy consumption by taking advantage of fast and low-loss propagation of light. They also have a potential to provide lower latency than conventional electronic transistor logic because the response speed is not restricted by the RC time constant of the signal line. This talk will describe a photonic-crystal-based optical logic circuit that is conceptually similar to pass transistor logic in electronics, which is utilized in reconfigurable logic systems such as field programmable gate arrays. Photonic crystal is an artificial dielectric made by nanotechnology, and it enables various nanophotonic devices owing to its tight light confinement effect. These wavelength-scale and integratable devices are promising for dense photonic networks in processor chips.
