2D photonic crystals deposited on polymer piezoelectric substrates - new kind of MOEMS

Abstract

Self-assembled polycarbonate films were deposited on polymer piezoelectric substrates under a fast dip-coating process. Ordered structures with micro- and nano-scaled holes dispersed in the polycarbonate matrix were obtained, demonstrating 2D hexagonal packaging. The process allows control of the hole size. Fabricated structures have a potential as 2D tunable photonic crystals. Bandgap formation in the near IR band was studied with a FTIR spectrometer. A distinct bandgap located in the vicinity of 1 /spl mu/m was revealed. Integration of photonic bandgap structure with MOEMS was achieved.
