Abstract

A process for selectively buried glass based planar waveguide chip manufacturing is presented, which involves surface channel waveguide forming and subsequent field assisted ion diffusion with aids of wedge shaped masking film Cross section at different portion of channel waveguide is observed with optical microscope, and waveguide transition loss is characterized. Results show that smooth transition has been realized using wedge shaped masking film with slope of 1/100, with transition loss of 2.8dB could be achieved..
