Abstract
A waveguide structure includes a glass body and a waveguide pattern formed in the glass body by irradiating a predetermined track on the glass body with sufficient energy to grow a crystalline phase along the predetermined track.
Claims27
A waveguide structure, comprising:
- a glass body;
- a waveguide pattern formed in the glass body by irradiating a predetermined track on the glass body with sufficient energy to grow a crystalline phase along the predetermined track.
An optical device, comprising:
- a waveguide structure comprising a glass body and a waveguide pattern formed in the glass body by irradiating a predetermined track on the glass body with sufficient energy to grow a crystalline phase along the predetermined track;
- and
- means for pumping radiation into the waveguide structure.
A laser device, comprising:
- an optical resonator;
- a waveguide structure disposed within the optical resonator, the waveguiding structure comprising a glass body and a waveguide pattern formed in the glass body by irradiating a predetermined track on the glass body with sufficient energy to grow a crystalline phase along the predetermined track;
- and
- means for pumping radiation into the optical resonator.
1 more element
A method for producing a crystalline phase in a glass body, comprising:
- moving a laser source relative to a glass body along a predetermined track on the glass body;
- and
- operating the laser source to provide sufficient energy to raise the temperature of the glass body along the predetermined track to grow a crystalline phase along the predetermined track.
