A novel polycarbonate (PC) was introduced to apply in the optical waveguide devices. PC has following distinct merits
than common polycarbonate: good processability, high thermal stability up to 293 C°; and high optical transparency.
Optical properties of absorption behavior and propagation loss were investigated in slab waveguides, and low
propagation losses of 0.335 dB/cm (@1550nm) and 0.197 dB/cm @632.8nm) have been achieved by using prismcoupler.
Additionally, straight optical waveguide and MMI coupler of ring resonator were fabricated using ultraviolet
(UV) cured resin Norland optical adhesive 61 (NOA61) as under or upper cladding layer and polycarbonate as
waveguide core-layer material through conventional methods such as spin coating, photolithography and reactive ion
etching (RIE). The process was studied in detail and the experimental results were given.
