Abstract

We demonstrate excitation of the azimuthally-polarized TE(01) cylindrical waveguide mode in hollow glass and metal waveguides with 780 nm light. Experimentally, we demonstrate formation of the vectorial vortex beams, and measure attenuation lengths of the TE(01) mode in hollow optical fibers with diameters of 50-100 microns. By silver-coating the inner walls of the dielectric fibers, we demonstrate a approximately 200% increase in the attenuation length.

摘要

我们展示了利用780纳米的光在中空玻璃和金属波导中激发方位角偏振的TE(01)圆柱波导模式。通过实验，我们展示了矢量涡旋光束的形成，并测量了直径为50 - 100微米的中空光纤中TE(01)模式的衰减长度。通过在介电纤维内壁镀银，我们展示了衰减长度增加了约200%。
