Improvement of Extinction Ratio of Wavelength-Selective Switch Using Quantum Well Double-Series-Coupled Microring Resonators

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a high-extinction-ratio hitless wavelength-selective switch with InGaAs/InAlAs multiple quantum well double-series-coupled microring resonators. It is also found that the change in coupling efficiency at couplers has a great effect on the switching characteristics.
