Architectural implications of nanoscale-integrated sensing and computing
(IEEE Micro, 2010-01-01) Pistol, C; Chongchitmate, W; Dwyer, C; Lebeck, AR
The authors explore nanoscale sensor processor (nSP) architectures. Their design includes a simple accumulator-based instruction-set architecture, sensors, limited memory, and instruction-fused sensing. Using nSP technology based on optical resonance energy transfer logic helps them decrease the design's size; their smallest design is about the size of the largest-known virus. © 2006 IEEE.

Modeling and simulation of a nanoscale optical computing system
(Journal of Parallel and Distributed Computing, 2014-01-01) Pang, J; Lebeck, AR; Dwyer, C
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.
