Combined thermomechanical and optical simulations of planar-optical polymer waveguides

Suar, Monali; Baran, Murat; Günther, Axel; Roth, Bernhard (Bristol : IOP Publishing Ltd., 2020)

In this work, we describe a theoretical approach for combined thermal, mechanical and optical simulation and analysis of planar polymer waveguides. We consider a finite element approach for thermal and stress/deformation ...
Simulation of straight and bent self-written waveguides in photopolymer mixture using phenomenological and diffusion models

Suar, Monali; Rahlves, Maik; Reithmeier, Eduard; Roth, Bernhard (Bellingham, Wash. : SPIE, 2018)

Straight and bent self-written waveguides (SWWs) are formed within a photomonomer mixture by means of a self-trapping effect when a single laser beam or two laser beams with tilt are propagated inside. These SWWs can be ...
