Spectral properties of liquid crystal photonic bandgap fibres with splay-aligned mesogens
- 55 Downloads
Through a detailed electromagnetic analysis we investigate the characteristics of liquid crystal infiltrated photonic crystal Fibers guiding by the Photonic Bandgap effect. The analysis, carried out using the Finite Element Method and including also material dispersion effects, puts into evidence particular spectral features related to the so-called splay alignment of the molecules constituting the liquid crystal, the so called mesogens. Control of these features is of use in the design of new devices for sensing or telecommunication applications.
