Abstract
The first observation of optical cutoff in thin‐film waveguides is reported. The waveguides consist of thin (∼10μ) epitaxial layers of high‐resistivity GaAs deposited on lower‐resistivity GaAs substrates. The optical cutoff is controlled through the electro‐optic effect by applying an electric field across the epitaxial layer.Keywords
