10 Gbit/s optical demultiplexing and switching by sinusoidally driven InGaAsP electroabsorption modulators

Abstract

10 Gbit/s optical demultiplexing and switching were performed by sinusoidally driven InGaAsP electroabsorption modulators, for the first time. An optical gate with variable gate width was obtained just with sinusoidal voltage. In-line demultiplexing/switching by the modulator was effective in reducing the amplified spontaneous emission noise in optical amplifier systems.
