Twisted split-ring-resonator photonic metamaterial with huge optical activity

Decker, M; Zhao, R; Soukoulis, C. M; Linden, S; Wegener, M


Coupled split-ring-resonator metamaterials have previously been shown to exhibit large coupling effects, which are a prerequisite for obtaining large effective optical activity. By a suitable lateral arrangement of these building blocks, we completely eliminate linear birefringence and obtain pure optical activity and connected circular optical dichroism. Experiments at around 100-THz frequency and corresponding modeling are in good agreement. Rotation angles of about 30 degrees for 205nm...[Show more]
