Abstract: The article describes the design and performance of an InGaAsP-InP 1 x 2 reconfigurable waveguide digital optical switch (RW-DOS) actuated by carrier-induced refractive index modulation. The optimized InGaAsP-InP devices are found to have required less than 20-mA drive current and exhibited better than 25-dB switching contrast ratio.
