Abstract

The bases for these inventions are a particular group of materials and their implementation to extract controllably or modulate laser radiation. The devices would be fabricated from a group of oxide compounds characterized by their narrow 3-D bands and having, typically, energy gaps within the range extending from 0.1 to 0.4 eV. A further common trait is their periodic table location, wherein the compounds tend to be oxides of elements in either group VB or IVB.
