Corrugation-Induced SiO Planar Long-Period Gratings for Photonic Applications

A long-period grating based on silica planar lightwave circuit technology is reported. The grating structure has been realized by forming a periodic corrugation on the lower waveguide cladding layer. This structure offers a permanent refractive index modulation, resulting in a grating that is highly...
