Hot Article: Simple route to ridge optical waveguide fabricated via controlled evaporative self-assembly

A new method to rationally design and fabricate silica ridge optical waveguides in a simple, cost-effective manner has been developed by researchers from the Republic of Korea and USA.

This new method is based on the controlled evaporative self-assembly of a polymer solution constrained in a cylinder-on-flat geometry with subsequent wet and dry etching of the sacrificial Ni–Cr film, polymer template and silica layer. Waveguides made in such a way may find potential applications as optical sensors.
