Characterization and estimation of refractive index profile of laser-written photopolymer optical waveguides
In this study, channel waveguides fabricated in photopolymer films by direct-writing using a low-power CW laser, are used as phase objects in a simple plane-wave diffraction setup, and the refractive index modulation ...
A fiber-integrated optical component fabricated via photopolymerization: Mode-selective grating coupler
We demonstrate a mode-selective directional coupler based on a grating structure, which is fabricated by laser direct-writing on a photopolymer thin film. The device is implemented on the flat planar surface of the D-Fiber, ...
Investigating the experimental limits of the Brewster’s angle method
We present the method, analysis, and experimental results of the Brewster’s angle method commonly used for determining the refractive indices of optical films. We show the significance of the intersection of reflectance ...
