We report on the fabrication of single-mode channel waveguide structures via the vacuum assisted microfluidic technique. The soft lithographic technique in conjunction with specially designed photomask patterns and UV curable epoxy resins can result in a high yield, cost-effective method for fabrication of channel waveguides. In particular, the use of microfluidic technique allows for the production of freestanding high quality single-mode channel waveguides on various substrates. The viscosity limitation of the microfluidic fabrication of small cross-sectional waveguide structures, especially single-mode channel waveguides at visible wavelengths, has been overcome through the introduction of sectional flow tapers.
