Nonlinear optical and electronic properties of SiC/PMMA/Ge/Fe waveguide for device applications

摘要

A new optical device whose dynamic grating intensity can be electrically controlled at specific magnetic fields and wavelengths has been demonstrated. This device has a semiconductor/polymer multilayer structure formed by pulsed laser deposition at room temperature. The reflection intensity can be electrically controlled with a response time of less than 2 ms. The EPR spectrum of the multilayer determined the concentration of the free spin and the effect of the light on the growth and decay of the Fe which was doped in the polymeric thin film using the high pulse laser deposition technique.
