Not Accessible

Your library or personal account may give you access

Abstract

An electrically tunable bandpass filter based on two photonic crystal fibers filled with different liquid crystals is demonstrated. Both the short-wavelength and long-wavelength edge are tuned individually or simultaneously with the response time in milliseconds.
