Abstract
The present invention relates to a method for trimming birefringence of an integrated optical device with at least one waveguide having a birefringence characteristic, comprising the steps of providing at least one electrode on top of the waveguide, and applying power equal to or above a predetermined power level to said at least one electrode for causing a change of the refractive indices of the waveguide.
Claims14
A method for trimming birefringence of an integrated optical device with at least one waveguide having a birefringence characteristic, comprising the steps:
- providing at least one electrode on top of the waveguide;
- and
- applying power equal to or above a predetermined power level to said at least one electrode to heat a region of the waveguide for causing an irreversible birefringence change of the waveguide.
An optical device for switching or filtering light passing through a waveguide having a birefringence characteristic, wherein the waveguide has been treated by providing at least one electrode on top of the waveguide and applying power equal to or above a predetermined power level to said at least one electrode to heat a region of the waveguide for causing an irreversible birefringence change of the waveguide.
