In this paper, a novel interference-based nanostructure was designed and simulated to realize an all-optical 2-bit reversible comparator by employing a novel technique. The plane wave expansion (PWE) ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Abstract: A phase-locked loop using a 1*2 optical switch is proposed as a high-frequency optical clock regenerator. A 1*2 LiNbO/sub 3/ optical switch and two photodetectors with a low-pass filter are ...
