Abstract
The invention discloses a semi-ring Fabry-Perot (SRFP) optical resonator structure comprising a medium including an edge forming a reflective facet and a waveguide within the medium, the waveguide having opposing ends formed by the reflective facet. The performance of the SRFP resonator can be further enhanced by including a Mach-Zehnder interferometer in the waveguide on one side of the gain medium. The optical resonator can be employed in a variety of optical devices. Laser structures using at least one SRFP resonator are disclosed where the resonators are disposed on opposite sides of a gain medium. Other laser structures employing one or more resonators on one side of a gain region are also disclosed.
Claims20
An optical device comprising:
- a medium including an edge forming a first facet that is reflective;
- a first waveguide within the medium, the first waveguide having first opposing ends formed by the first facet;
- a coupling region to the first waveguide;
- and
- a second waveguide coupled to the fist waveguide by the coupling region where the second waveguide avoids intersecting the first facet and has both of second opposing ends formed by facets other than the first facet.
An optical device comprising:
- a first waveguide means for carrying light within a medium including an edge forming a first facet that is reflective, the first waveguide means having first opposing ends formed by the first facet;
- a second waveguide means for carrying the light where the second waveguide means avoids intersecting the first facet and has both of second opposing ends formed by facets other than the first facet;
- and
- a coupling region means for coupling the light between the first waveguide and the second waveguide.
