Spectral tuning of liquid microdroplets standing on a superhydrophobic surface using electrowetting
A. Kiraz, Y. Karadag, and A. F. Coskun
Using electrowetting, we demonstrate reversible spectral tuning of the whispering gallery modes of glycerol/water microdroplets standing on a superhydrophobic surface by up to 4.7 nm at 400 V. Our results can inspire electrically tunable optical switches and filters based on microdroplets on a sup ... [Appl. Phys. Lett. 92, 191104 (2008)] published Tue May 13, 2008.
