Abstract

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 cavity; this enables the resonator to have a high optical activity. The numerical result shows that the strong lasing at 1550 nm may be achieved when the cavity array is pumped at 980 nm. This double resonance nanolaser array has potential applications in future optical devices and quantum information techniques.
