Modeling and simulation of a nanoscale optical computing system
Abstract
Optical nanoscale computing is one promising alternative to the CMOS process. In this
paper we explore the application of Resonance Energy Transfer (RET) logic to common
digital circuits. We propose an Optical Logic Element (OLE) as a basic unit from which
larger systems can be built. An OLE is a layered structure that works similar to a
lookup table but instead uses wavelength division multiplexing for its inputs and
output. Waveguides provide a convenient mechanism to connect multiple OLEs into large
circuits. We build a SPICE model from first principles for each component to estimate
the timing and power behavior of the OLE system. We analyze various logic circuits
and the simulation results show that the components are theoretically correct and
that the models faithfully reproduce the fundamental phenomena; the power-delay product
of OLE systems is at least 2.5× less than the 14 nm CMOS technology with 100× better
density. © 2013 Elsevier Inc. All rights reserved.
