Abstract
Electro-refractive and electro-absorptive modulation is demonstrated i n Schottky-contacted, strained MBE-grown ZnSe waveguides with cladding layers of ZnMnSe on n-GaAs substrates. Utilizing the Pockels effect i n the transparent region of the waveguide with built-in birefringence, a contrast ratio better than 80:1 at 2.485 eV is achieved. The rise t ime of 4.7 +/- 0.5 ns is RC limited. The narrow optical bandwidth of 6 meV makes the modulator wave length-selective.
