Athermalized optical waveguide devices and methods of making the athermalized devices are described. Boron is incorporated into the composition of the optical waveguides in order to athermalize the waveguides by reducing spectral shifts caused by changes in temperature. The invention includes the utilization of boron dopants in the core and cladding of optical waveguide devices such as Mach-Zehnder coupler devices and long period fiber gratings.
L'invention est constituée par des guides de lumière athermalisés et des méthodes de fabrication de ces guides de lumière. Du bore est incorporé à la substance dont sont faits les guides de lumière pour athermaliser ceux-ci en réduisant les décalages spectraux causés par les variations de température. L'invention comprend l'utilisation de dopants de bore dans l'âme et la gaine de guides de lumière tels que les coupleurs de Mach-Zehnder et les réseaux de fibres à grande période.
