Abstract
In accordance with the present invention, one or more laser diodes are efficiently coupled into a waveguide amplifier in order to provide either an efficient amplifier or a laser. Light from one or more laser diodes is efficiently coupled into one or more waveguides through the effects in the refractive index between the core material of the waveguide and the cladding material around the waveguide. Both the core material and the cladding material can be deposited with a high degree of uniformity and control in order to obtain the coupling.
Claims20
An optical waveguide device, comprising,
- at least one laser diode;
- and
- at least one high refractive index contrast slab waveguide coupled to receive light from the at least one laser diode,
- wherein the slab waveguide is deposited by biased pulsed DC plasma vapor deposition.
A method of coupling pump light into a gain medium, comprising:
- depositing the gain medium by a biased pulsed-DC plasma vapor deposition process;
- forming a high refractive index contrast waveguide from the gain medium;
- and
- directing pump light into the high refractive index contrast waveguide.
