Abstract

We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an ε-GaSe crystal and operated at the 1.960-eV line of a He–Ne laser. We demonstrate that the modulation in an Al–ε-GaSe–Cu device results mainly from the Franz–Keldysh effect. Relatively high speed and low operating voltage could make these modulators with Schottky-barrier contacts attractive devices in the red range of the spectrum.
