A method to retrieve optical and geometrical characteristics of three layer waveguides from m-lines measurements
Thomas Schneider, Dominique Leduc, Cyril Lupi +3
We consider three layer optical waveguides and present a method to measure simultaneously the refractive index and the thickness of each layer with m-lines spectroscopy. We establi…
Optical characterization of PZT thin films for waveguide applications
Julien Cardin, Dominique Leduc, Thomas Schneider +3
In order to develop an electro-optic waveguide, Pb(Zr, Ti)O3 ceramic ferroelectric thin films were elaborated by a modified sol-gel process on glass substrate. In the aim to study…
Theoretical investigation of the more suitable rare earth to achieve high gain in waveguide based on silica containing silicon nanograins doped with either Nd3+ or Er3+ ions
Alexandre Fafin, Julien Cardin, Christian Dufour +1
We present a comparative study of the gain achievement in a waveguide whose active layer is constituted by a silica matrix containing silicon nanograins acting as sensitizer of eit…
Modeling of the electromagnetic field and level populations in a waveguide amplifier: a multi-scale time problem
Alexandre Fafin, Julien Cardin, Christian Dufour +1
A new algorithm based on auxiliary differential equation and finite difference time domain method (ADE-FDTD method) is presented to model a waveguide whose active layer is constitu…
