Proposes a novel optical switching device using MEMS phase shifters to achieve π-shift, suggesting improved performance in optical technologies.
We propose a novel type Mach-Zehnder interferometric optical switching device using micro-electro mechanical systems (MEMS) as a phase shifter. As the analytical result, the amount of stretch length is 70nm at the applied voltage of 60 V per one phase shifter. The π-shift is achieved using cascade connections of 4-7 shifters.
