Polymeric Waveguides with Bragg Gratings in the Middle of the Core Layer

Abstract

In this paper we proposed a new Bragg grating waveguide in order to improve reflectivity and to achieve compactness. Bragg gratings with various thicknesses were engraved in the middle of the core layer with a length of 3 mm. For the sake of cost-effectiveness, the 3 rd order Bragg grating waveguides were fabricated via conventional photolithography. The maximum reflectivities for the fixed width waveguide of 6 μm with the 0.1 and 0.3 μm-thick Bragg gratings were, -13.14 and -6.25 dB, respectively, and the Bragg wavelengths were 1562.28, 1564.10 nm, respectively. A slight increase in the Bragg grating thickness can result in a remarkable reduction in the length of the Bragg grating waveguide with a fixed reflectivity.

“…The cladding polymer material is a UV-curable fluorinated resin based on acrylate supplied by ChemOptics Inc., trademarked ZPU13-450, which has a low refractive index of 1.451 and a material loss of 0.1 dB/cm at a wavelength of 1.3 μm [15]. The thickness of the lower-and upper-cladding was 30 μm.…”
