Abstract

The measurements of intersubband (IS) transitions in the communications wavelength range were presented using GaN/AlGaN multiple quantum wells (QW). Peak absorption wavelengths as short as 1.35 and 1.52 μm were measured for a symmetric double QW of 12 Å wide wells coupled by a 10 Å wide barrier. The IS absorption spectrum of double QW was presented.
