1. An optical device, comprising:

  • a light emitting device comprised of at least an active region;

    at least one first shaped optical element coupled to at least one side of the light emitting device;

    at least one second shaped optical element encapsulating both the light emitting device and the at least one first shaped optical element for extracting light emitted by the active region and the first shaped optical elements; and

    a phosphor, optically coupled to the at least one second shaped optical element, wherein light in at least a first wavelength region emitted by the III-nitride light emitting region passes through the at least one second shaped optical elements and excites the phosphor to emit light in at least a second wavelength region.
