The infrared spectral region is important for a number of applications, both military and civilian. In this talk, we will discuss the development of new optical materials and active optoelectronic devices that function across this region. In the first part of this talk, we will discuss novel synthesis techniques for chalcogenide-based polymers and their properties, which include wide infrared transparency windows and extremely high refractive indices. To conclude the seminar, we will discuss refractive non-mechanical beam steering devices. These devices, based around liquid-crystal clad thin film waveguides, have many advantageous properties over traditional, mechanical beam steerers, with greatly reduced size, weight, and power requirements. Here, we will cover the operation principles, design, fabrication, and steering properties of these devices, which represent a fusion of materials synthesis, processing, and optical design.
