We report here on the use of nanoimprint technologyto fabricate low cost planar waveguides in a Polysiloxane polymer system capable of passing the stringent Telcordia environmental and reliability criteria. Low loss buried channel waveguides with core cross sections of 3x3 microns and a 2% refractive index contrast were fabricated on bare silicon wafers with a simple and fast four step process using a 100mm diameter Polydimethylsiloxane (PDMS) stamp. The waveguides were patterned using an...[Show more]
