Planar Optical Waveguide Manufacturing Process
This article explores the main fabrication methods for polymeric optical waveguides, such as traditional and maskless photolithography, laser ablation, hot embossing, nanoimprint lithography, the Mosquito method, inkjet printing, aerosol jet printing, and. Planar waveguides, also known as slab waveguides, are a fundamental component in the field of photonics. These structures are essential for guiding light in a controlled manner, and they have a wide range of applications in optical communications, lasers, and other photonic devices. While Bragg gratings are routinely patterned within optical fibers using the point-by-point or line-by-line technique, the objective of our work is to produce Bragg grating sensors within planar glass substrates. In principle, they function just like fibers and are also described by the same parameters.
