Lasing from dye-doped photonic crystals with graded layers in dichromate gelatin emulsions
Mang Hin Kok, Weixin Lu, Jeffrey Chi Wai Lee, Wing Yim Tam, George K. L. Wong et al.
We report on optically pumped lasing from dye-doped, graded-spacing layer structures of dichromate gelatin emulsions fabricated using two-beam holographic interference. The graded layers exhibited deep and wide photonic band gaps. Multimode lasing with both a low threshold and a high quality factor ... [Appl. Phys. Lett. 92, 151108 (2008)] published Thu Apr 17, 2008.
