Ultrasmall square-lattice zero-cell photonic crystal laser

Ho-Seok Ee, Kwang-Yong Jeong, Min-Kyo Seo, Yong-Hee Lee, and Hong-Gyu Park
We report optically pumped room-temperature lasing in a square-lattice photonic crystal cavity consisting of two shifted lattice points and heterogeneous lattices with different air hole sizes. Three-dimensional finite-difference time-domain simulation shows that this cavity has an ultrasmall mode v ... [Appl. Phys. Lett. 93, 011104 (2008)] published Tue Jul 8, 2008.
