ABSTRACT:
An apparatus comprising an optical-mode-converter structure. The optical-mode-converter structure includes a tapered optical core on a planar substrate, an optical cladding layer covering the tapered optical core and a mode-expanding layer. The mode-expanding layer covers the tapered optical core and is located in-between the tapered optical core and the optical cladding layer. The mode-expanding layer has a refractive index that is in-between a refractive index of the tapered optical core and a refractive index of the optical cladding layer.
