Double-resonance nanolaser based on coupled slit-hole resonator structures

Z. H. Zhu, H. Liu, S. M. Wang, W. M. Ye, X. D. Yuan, S. N. Zhu
This work investigates a kind of metallic magnetic cavity based on slit-hole resonators. Two orthogonal hybrid magnetic resonance modes of the cavity with a large spatial overlap are predesigned at the wavelengths of 980 and 1550 nm. The Yb:Er codoped material serving as a gain medium is set in the ... [Opt. Lett. 35, 754-756 (2010)]
