Abstract :
We demonstrated a torsional micromechanical tunable optical filter with potentially far large tuning range and free of damages resulting from capacitor discharge. The tuning range is above 100 nm and was limited by the tunable source available for testing. The insertion of the filter in an optical data link causes no power penalty. The torsional MEMS design can be readily transferred to a tunable VCSEL and detector designs to lead to a wider tuning range and to eliminate the reliability issues. This program was supported by NSF and DARPA. Carlos F.R. Mateus is supported by CAPES Foundation and Brazilian Air Command.
