Spin-crossover molecular complexes for visible-light modulators
Résumé
Phase Change Materials are materials that exhibit a large optical change in their complex index of refraction upon switching between their various electronic or structural states. As such, they offer a promising way to implement tunability and reconfigurability in the next generation of nano-photonic devices.
In this contribution, we will review our recent studies on spin-crossover molecular compounds that can be evaporated and micro-structured. We will also report their use to make resonant and broadband thermo-optic modulators operating in the visible wavelength range respectively based on metal-mirror Fabry-Perot interferometers and frustrated total internal reflection systems.
