| Abstract: | The finite-difference time-domain method was employed to simulate the field distribution of light near the output face of a very small aperture laser diode. By conducting simulations, the characteristic of near field in the aperture was illustrated. The dependence of field distribution and spatial resolution on the aperture size and the thickness of metal film were produced, also some optimized conditions for device fabrication and design were achieved. |
