Title:
EXCITONIC MACH ZEHNDER MODULATOR
Document Type and Number:
WIPO Patent Application WO/2023/196774
Kind Code:
A3
Abstract:
An integrated excitonic Mach Zehnder modulator includes a heterostructure of material to create an exciton or optical input and output and two arms for excitons between the input and the output. An interference control electrode on one of the arms is used to control exciton or optical output. The materials are selected and arranged such that combining excitons at the output is controlled by voltage applied to the interference control electrode such that exciton matter waves are in phase and the interference is constructive when the output signal is on, and when the exciton matter waves are out of phase the interference is destructive and the output signal is off.
