ABSTRACT:
A device is described based on flexible photonic crystal, which is comprised of a periodic array of high index dielectric material embedded in a flexible polymer. Dynamic, real time tunability is achieved by the application of a variable force with a MEMS actuator or other means. The force induces changes in the crystal structure of the photonic crystal, and consequently modifies the photonic band structure. The concept was demonstrated by a theoretical investigation on the effect of mechanical stress on the anomalous refraction behavior of the flexible PC, and a very wide tunability in beam propagation direction was observed. Experimental studies on fabrication and characterizations of the flexible photonic crystal structures were also carried out. High quality flexible PC structures were fabricated by e-beam lithography and anisotropic etching processes.
