Abstract

We demonstrate polymeric single-mode waveguides with low loss at visible wavelength. Inverted ridge waveguides were fabricated by a low-cost UV-imprinting method. An average propagation loss of 0.19 dB/cm was obtained at 638 nm wavelength by investigating the transmission properties of spiral waveguides with the overall length of 23.3 cm. Payne-Lacey scattering model predicts that the scattering loss due to imprint replication is dominated by the sidewall roughness. It is envisaged that the used low-cost fabrication method and waveguide configuration can have potential in power budget sensitive applications.
