Paper Abstract

Bending loss is the biggest drawback to hollow waveguides used for light delivery applications such as laser ablation. One way to overcome this limitation without changing the fiber design or fabrication is to engineer the input light to excite specific modes with better optical properties. Our first order calculations of the transmission and bending losses inside the cylindrical hollow waveguides showed that the TE01 mode suffers the least amount of losses. To selectively excite this mode, it is desired to design an optical component that converts incident linearly polarized light into a rotating wave similar to the TE01 mode. This work focuses on the design and fabrication of a subwavelength structure that converts the input polarization into that of the TE01 mode.
