ABSTRACT:
A new family of lasers and optical parametric oscillators is based on efficient frequency conversion or doubling in multimode compound optical waveguides. These waveguides exploit specific useful properties of their higher order modes while providing good compatibility with single-mode optical fibers. A mode engineering approach is applied to construct a compound waveguide structure that supports a higher order mode having a sharp peak in its field. This sharp peak simplifies selection of this mode by efficient coupling of its radiation into a single-mode fiber. The lasers and optical parametric oscillators employ wavelength selective properties of this mode field configuration and its unique ability to support efficient frequency conversion and doubling.
