Sensing high electric fields using lithium niobate
In a collaboration with the High Voltage Laboratory at the department of Information Technology and Electrical Engineering (D-ITET), we have used our photonic integrated circuits to optically measure electric field strengths.
Bragg gratings and microring resonators have been fabricated on the lithium niobate-on-insulator platform and compared in terms of their suitability for this task.
