Abstract
We discuss the potential use of nonlinear optical phase conjugation to enhance the performance of various classes of optical interferometric sensors and optical fiber biosensor devices, with potential application to trace-compounds detection of explosives and other species. Examples include Michelson interferometers, laser homodyne sensors, ellipsometers, and modulation spectrometers. We speculate that compensated interferometric devices using nonlinear optical phase conjugation may lead to a new class of fieldable remote sensor which is robust, compact, inexpensive, and portable, with the capability of functioning in real-world environments. In addition to explosive sensors, these compensated remote sensors have potential application for in situ monitoring of (epitaxial) growth processes, etch and wear operations, drug interdiction, impurity sensing, and environmental monitoring.
