We designed and fabricated silicon-on-insulator based Michelson interferometer (MI) thermo-optical switches with deep etched trenches for heat-isolation. Switch power was reduced ~20% for the switch with deep etched trenches, and the MI saved ~50% power than that of the Mach-Zehnder interferometer. 10.6 mW switch power, ~42 µs switch time for the MI with deep trenches, 13.14 mW switch power and ~34 µs switch time for the MI without deep trenches were achieved.
