Abstract

original image

An inorganic glass film with engineered multiple photonic bandgaps (MPBGs) is fabricated by sol–gel processing. This sol–gel film consists of TiO2, SiO2, and mixed SiO2–TiO2 films and has controllable characteristics of MPBGs in the overall visible region. By using the sol–gel film as a resonator, a red–green–blue pixelated liquid-crystal laser is also demonstrated.
