1. An optical device comprising:
a first waveguide region having a core comprising a first material, the first material is crystalline silicon;
a second waveguide region having a core comprising a second material, wherein:
the first material and the second material are crystalline structures;
the second material is different than the first material;
the second material is an epitaxial structure having a direct bandgap comprising two or more elements; and
the second waveguide region is spatially separated from the first waveguide region by a separation region; and
a connecting waveguide disposed in the separation region, wherein:
the connecting waveguide comprises a core and a cladding;
the core of the connecting waveguide is end coupled with the core of the first waveguide region; and
the core of the connecting waveguide is end coupled with the core of the second waveguide region.
