Novel Multiple Quantum Well (MQW) optical modulators for use in time-division optical fiber interconnects will be presented. A bit-error-rate analysis of a time-division receiver indicates high contrast ratio optical gates are required for high-speed interconnect applications. A high contrast MQW gate, consisting of a nonlinear asymmetric reflection modulator, suitable for use in optical time-division systems will be presented which utilizes the GaAlInAs alloy lattice-matched to InP. This system is ideal for optical interconnect applications since MQW materials and devices are easily designed for operation in the optical fiber transmission windows of 1.3 and 1.5 μm. Utilizing Asymmetric Double Quantum Wells (ADQWs) as the nonlinear spacer for the asymmetric reflection modulator will also be discussed. The recovery time of ADQWs can be tailored for interconnect applications by choosing the optimum width of the tunnel barrier. Electrooptic modulators which utilize real space transfer of electrons in ADQWs will also be presented.
