Design of 130–290 GHz Rectangular COC Fibers for High-speed Data Links

A rectangular polymer fiber based on COC material is proposed for short-distance polarization-maintaining communication links. Numerical study is implemented to find out the optimum dimension of the dielectric core. The proposed millimeter-wave rectangular waveguide posses low modal loss of 0.13 – 2.54 dB/m, reasonably low dispersion and high birefringence for the D-band frequency range (130–170 GHz). Measured loss from our preliminary characterization agrees well with the calculated values up to 290 GHz. Considering the recent advances in fiber drawing techniques, these fibers can be fabricated in large quantities and thus has the potential to pave the path for polarization-sensitive, low-loss and low-dispersion THz interconnects and short-range, high-speed data links.
