Strain-induced modified form birefringence in a one- dimensional photonic crystal: An exact coupled-mode approach
Résumé
We use an exact coupled-mode theory to describe the effect of interfacial strain on the optical properties of a one-dimensional photonic crystal, with special emphasis on modified form birefringence coming from strain-induced local anisotropy. Parallel and perpendicular states of polarization being totally decoupled, we easily extract in each case an effective coupling constant and an effective detuning from the transfer matrix of the unit cell.
