英文摘要	An adiabatic elliptical optical coupler device (101) is provided comprising: a substrate (103) having an edge (105); a first waveguide (111) on the substrate, the first waveguide comprising a constant-width region (131) and a tapered region (133) terminating at the edge (105) of the substrate, the tapered region having a smaller width at the edge than at the constant-width region (131); a pair of second waveguides (150) on the substrate, and located on either side of the tapered region (133) of the first waveguide (111), each of the pair of the second waveguides terminating at the edge at a first end (151) and extending to a second end (152) adjacent the constant-width region (131) of the first waveguide (111), and distal the first end (151); at least a portion of each of the pair of second waveguides being tapered, and optically coupled to the first waveguide (111) to transition a mode of an optical signal in the first waveguide from an elliptical mode at the edge (105) towards a confined mode.
