Abstract

We report on the development of channel waveguides in a lead–silicate glass through the extrusion technique. An extruded glass slab with four imbedded fibers each with core size of 8 by 2.5µm in the horizontal and vertical directions was manufactured. These neodymium-doped channel waveguides were in single-mode operation at 808nm and had attenuation of 0.1dB cm–1 at 1.06µm. The measured 4F3/2 lifetime of 488µs and emission cross section of 2.5×10–20 cm2 were in good agreement with reported values. The integration of multiple glass variants into a single compact platform is presented as a manufacturing route for complex integrated optical waveguides.
