Direct-bonded square, rectangular, polygonal, and noncircular optical interfaces provide better matching with rectangular waveguides and better performance. Direct oxide-bonding processes can be applied to create running waveguides, photonic wires, and optical routing in an integrated circuit package or in chip-to-chip optical communications without need for conventional optical couplers.
