An electronic device comprises a photonic integrated circuit (PIC) including at least one optical signal source, an emitting lens disposed on the PIC to steer light emitted by the at least one optical signal source in a direction substantially parallel to a first surface of the PIC, and an optical element disposed on the PIC and having a curved surface in a shape of a quarter cylinder that is configured to steer light emitted from the emitting lens in a direction substantially orthogonal to the first surface of the PIC.
