We present a survey on organic composite and hybrid materials suitable for a new family of optical devices like thermo- and electro-tunable multilayer mirrors, microcavities and optical filters. The main component is a tunable and/or switchable Bragg grating. Two different classes of materials have been realized, characterized, and designed in form of prototype devices, namely a) polymer-liquid crystal composite and b) liquid crystal infiltrated porous silicon. Different geometries and patterns can be envisaged, leading to different physical properties and a large number of device potentialities, most of them yet unexplored.
