| description | This paper, presents a preliminary guide to tune the band gap of photonic crystals for optoelectronic applications. This study includes the theoretical calculations to determine the optical constants of a material, synthesis of a new photonic crystal, and a technique for photonic band gap tuning which is minimally required for developing the optoelectronic device. It is observed from the optical studies that the band gap can be tuned by the replacement of the functional group in the compound. It is confirmed that this new crystal has the maximum transparency in the entire visible region and hence it should exhibit a non-linear optical property. The presence of moieties with intermolecular hydrogen bonding in the lattice of such compounds is responsible for the second harmonic generation (SHG). |
