Research output: Contribution to journalConference articlepeer-review


Based on unbalanced Mach-Zehnder interferometers, a novel electrooptical waveguide tunable filter is proposed and designed. By coupled-mode equations method and beam propagation method, the variation of the output light intensity versus applied voltage and frequency is analyzed for a single filter. Then several filters are combined to filtrate and route one of several frequencies, and a good result is obtained.
