We developed an amorphous polymer of cyclized perfluoropolymer, which is highly transparent throughout the visible range, and fabricated waveguides of the polymer for visible light. At a wavelength of 405 nm, approximately 60% of lightwaves are propagated through the straight waveguide and over 50% of the lightwaves are propagated through the buried waveguides with a radius of more than 30 mm, demonstrating the feasibility of the waveguides as light sources with a small angle of a beam divergence in a single mode. The waveguides are prospective candidates for multiple beams in line for parallel information processing, such as optical recording systems.
