Miniature Mach-Zehnder InGaAsP quantum well waveguide interferometers for 1.3 mu m

Electrooptic Mach-Zehnder interferometers with active lengths as small as 350 mu m are discussed. These strip-loaded waveguide devices utilize the electrooptic effect in InGaAsP/InP quantum wells to achieve pi phase shift with single arm drive voltages of 12 V and 6 V drive in push-pull operation.<
