✦ Synopsis

We have fabricated surface plasmon modulated
nano-aperture vertical-cavity surface-emitting lasers (VCSELs)
from common 850 nm VCSELs using focus ion beam etching with Ga^+^
ion source. The far-field output power is about 0.3 mW at a
driving current of 15 mA with a sub-wavelength aperture surrounded
by concentric periodic grooves. The enhancement of transmission
intensity can be explained by diffraction and enhanced fields
associated with surface plasmon. This structure also exhibits
beaming properties.
