Microstructures in Polymer Fibres for Optical Fibres, THz Waveguides, and Fibre-Based Metamaterials
Figure 3
(a) A single-mode mPOF made of PMMA for the visible using the hexagonal hole array. The original cane was sleeved twice, firstly with a PMMA jacket and finally with a PC outer jacket. (b) An all-solid single-mode mPOF using a composite core consisting of Zeonex rods in a PMMA background. The right image shows the far field at 650 nm, showing single-mode operation. Figures adapted from (a) [11] and (b) [41].
