Abstract

The effect of metal thickness on the transmitted optical field of a sub-wavelength metal aperture on a Very Small Aperture Laser (VSAL) is modeled and studied experimentally. The experimental results were obtained in the far field, on a VSAL fabricated from a commercial semiconductor diode laser using Focused Ion Beam Etching (FIBE). The optical field in the near-field region of the VSAL was modeled by the Finite Difference Time Domain (FDTD) method. In this model, the laser was assumed to be decoupled from the aperture.
