Widely tunable long period gratings using 3D printed periodic grooved plates

Abstract: In this work we present mechanically induced Long Period Gratings (LPGs) realized in different kinds of glass optical fibers by using UV-cured 3D printed periodic grooved plate. The periodic modulation of the geometry and refractive index along the length of the optical fiber is induced by pressure applied transversely to the grooved plate and leads to light coupling between the core mode and co-propagating cladding modes at specific resonance wavelengths. Using the proposed method, we realize and analyze in d… Show more
