Transversely quasicrystallographic 3D photonic chiral lattices: Polarization-controllable complex photonic band gap structures

In view of new generation integrated photonic devices, we present our computational as well as fabrication results on the investigation of photonic chiral lattices with diverse transversely quasicrystallographic symmetries. As the photonic band gap becomes becomes more symmetric as well as the directional tunability is enhanced in photonic quasi crystals (PQC), they would give an additional degree of freedom for transversely PQC 3D chiral lattices in tuning frequency as well as polarization band gaps for optimized polarization controlled integrated optical devices.
