Investigation of thermal stability of UV written planar waveguides using direct grating writing

Investigation of thermal stability of UV written planar waveguides using direct grating writing

We use the direct grating writing technique, based on direct UV writing, to define planar Bragg channel waveguides and accurately probe the refractive index to characterise thermal waveguide erasure and material properties.
