Metal-print-defining thermo-optic tunable chirped waveguide Bragg gratings using organic-inorganic hybrid PMMA materials

High-birefringence waveguide Bragg gratings for the C-band are fabricated in the Silica-on-Silicon platform with Displacement Talbot Lithography (DTL). Transmission and reflection spectrums of the Bragg wavelength splitting were measured and calculated. The birefringence here is up to 7.919×10−4 to 1.670×10−3, much higher than existing devices via other platforms. We illustrate the principle and advantage of DTL though theoretical analysis and numerical simulation. The birefringence of waveguide Bragg gratings here are customized with their device configuration (i.e., waveguide width and grating etched depth), enabling an effective method to construct scalable Silica-on-Silicon devices for highly linear-polarized external-cavity semiconductor lasers.
