Hitless Wavelength-Selective Switch Using Multiple Quantum Well Second-Order Series Coupled Microring Resonators

摘要

A hitless wavelength-selective switch (WSS) based on InGaAs/InAlAs multiple quantum well (MQW) second-order series-coupled microring resonators is proposed. The WSS is operated by an electrorefractive index change in the MQW core layer due to the quantum-confined Stark effect (QCSE). The hitless switching of the WSS was successfully demonstrated for the first time.
