Lasing from a One-Dimensional Photonic Crystal Made of Dye-Doped Holographic Polymer-Dispersed Liquid Crystal Gratings

摘要

Lasing action was observed in a one-dimensional photonic crystal made of rhodamine B dye-doped holographic polymer-dispersed liquid crystal gratings. The results showed that the lasing peak centered at about 604 nm, with a full width at half maximum of about 6.0 nm. The threshold pumping energy was about 80 μJ at the pumping wavelength of 532 nm. Theoretical simulation showed that the lasing from this structure happened at the photonic bandedge of the one-dimensional photonic crystal. The lasing modes were also investigated.
