摘要：

Layered crystals of GaSe are grown by the Bridgman method. Transmission spectra are measured for various sample configurations with respect to the c-axis, applied electric field, direction of incident light and polarization. Absorption edge shifts toward longer wavelength by 20 nm under an electric field of 1 kV/cm, the shift of which is two orders larger than estimated on the Franz-Keldysh mechanism. Switching time is measured to be 53 ns or less.
