Abstract:
1. An optical chip, comprising: a first large mode field size dielectric waveguide to interface with an external optical device; at least one low minimum bending radius dielectric waveguide having a first end coupled to the first large mode field size dielectric waveguide, the low minimum bending radius dielectric waveguide being used for one or more of a bend and a split of a light path; a second large mode field size dielectric waveguide coupled to a second end of the low minimum bending radius dielectric waveguide; and at least one optical function connected to one or more of the first large mode field size dielectric waveguide and the second large mode field size dielectric waveguide; wherein the optical function is split into at least two pieces, with the at least two pieces separated by the low minimum bending radius waveguide; wherein the first large mode field size dielectric waveguide, the second large mode field size dielectric waveguide, the low minimum bending radius dielectric waveguide, and the optical function are fabricated monolithically on a single substrate.
