摘要： The present disclosure relates to silicon-based photonic chips, in particular, for optically coupling to an optical fiber or optical fiber assembly, and a method for fabricating the same. The photonic chip of the disclosure comprises a single-mode waveguide configured to guide light and provide a light beam. Further, the photonic chip comprises a first optical element configured to expand the light beam in a first direction in-plane of the photonic chip, in order to provide an expanded light beam. The photonic chip also comprises a second optical element configured to deflect and at the same time further expand the expanded light beam in a second direction, in order to provide an output light beam from the photonic chip.
