Abstract: Embodiments disclosed herein generally relate to an optical device for transferring light between a first and second waveguide. The optical device may generally include the first waveguide, a first support member and a base on which the first waveguide and first support member are disposed. The optical device may further include a second support member wherein the first support member is disposed between the second support member and the base. The second support member comprises at least one groove. The second waveguide may be disposed at least partially in the groove such that the second waveguide is between the first and second support members. The optical device may further include at least one lens disposed between the first waveguide and the second waveguide to transfer an optical signal between the first and second waveguides through the lens.

Abstract: An optical device may include an optical bench used align a photonic chip to a receptacle. In one embodiment, a surface of the optical bench defines an alignment plane. When a fiber stub in the receptacle is disposed on the surface, an optical path in the stub is parallel with the alignment plane. By disposing the photonic chip on the same surface, the chip and the stub can be aligned such that optical signals can be transmitted between the stub and an optical component (e.g., light source or waveguide) in the photonic chip. In one embodiment, the optical path in the stub and the optical component may have the same height relative to the optical bench. Moreover, the optical device may include a direct thermal connection between the assembly and the heat sink, and thus, have better thermal coupling relative to using thermal pads.

Abstract: An apparatus for providing single mode optical signal coupling between an opto-electronic transceiver and a single mode optical fiber array takes the form of a lens array and a ferrule component. The lens array includes a plurality of separate lens element disposed to intercept a like plurality of single mode optical output signal from the opto-electronic transceiver and provide as an output a focused version thereof. The ferrule component includes a plurality of single mode fiber stubs that are passively aligned with the lens array and support the transmission of the focused, single mode optical output signals towards the associated single mode optical fiber array.
