MODIFIED TRANSISTOR OUTLINE (TO)-CAN ASSEMBLY FOR USE IN OPTICAL COMMUNICATIONS AND A METHOD

摘要

A modified TO-can assembly is provided that has greater versatility with respect to spatial constraints than known TO-can assemblies and that is suitable for use in a wider range of applications than known TO-can assemblies. The modified TO-can assembly has a receptacle that has been modified to receive an optical fiber through its side instead of through its end. Within the TO-can assembly, the optical path is folded in order to couple the light between the optoelectronic component of the TOSA or ROSA and the end of the optical fiber. The combination of these features provides the modified TO-can assembly with a compact profile that makes it more versatile with respect to spatial constraints and therefore suitable for use in a wider range of applications.

主权项

1. A modified transistor-outline (TO)-can assembly comprising:
a bottom portion comprising an upper surface, a lower surface, an inner surface, and an outer surface, the inner and outer surfaces of the bottom portion defining a side wall of the bottom portion; a window having at least an upper surface and a lower surface, the upper surface of the window being mechanically coupled to an inside of the upper surface of the bottom portion about a peripheral portion of the window; an optical subassembly (OSA) affixed to an inside of the lower surface of the bottom portion, the OSA including at least an optoelectronic device; and a receptacle mechanically coupled to an outside of the upper surface of the bottom portion, the receptacle having at least an upper surface, a lower surface, and an outer wall defining a side wall of the receptacle, the receptacle including an opening formed in the side wall for receiving an optical fiber, and a first reflector formed on an inside of the upper surface of the receptacle and positioned to reflect light received by or transmitted from the OSA.
