1. An optoelectronic module assembly comprising:
a housing comprising a base portion having at least an upper surface and a lower surface, and a wall portion extending from the upper surface of the base portion defining a space within the housing;
an optoelectronic device assembly disposed in the space within the housing and on the upper surface of the base portion of the housing, the optoelectronic device assembly including at least an optoelectronic device, wherein the space being transparent to an operational wavelength of the optoelectronic device;
wherein a coupling portion of the wall portion of the housing has at least an inner surface, and an outer surface, the inner and outer surfaces of the coupling portion defining a side wall of the coupling portion;
an optical fiber alignment assembly having at least a top ferrule portion and a bottom ferrule portion facing the top ferrule portion, wherein an opening is formed in the side wall of the coupling portion of the wall portion of the housing, wherein the optical fiber alignment assembly is received in the opening of the coupling portion, wherein the optical fiber alignment assembly is inserted through the opening in the sidewall of the coupling portion of the wall portion of the housing and the top and bottom ferrule portions are hermetically sealed at the opening in the side wall of the coupling portion of the wall portion of the housing, with a portion of the top ferrule portion and the bottom ferrule portion remaining outside the housing,
wherein the optical fiber alignment assembly receives a portion of an optical fiber in the optoelectronic module assembly at a non-zero degree angle, α, relative to an axis of the optoelectronic module assembly that is generally normal to the base portion of the housing, wherein the portion of the optical fiber that is received by the optical fiber alignment assembly is received in a groove formed in the top ferrule portion of the optical fiber alignment assembly, wherein the top ferrule portion of the optical fiber alignment assembly has a reflector at an extended portion extending beyond the bottom top ferrule portion into the space of the housing, wherein the reflector folding an optical pathway within the optoelectronic module assembly by the angle α, the groove formed in the top ferrule portion having a length-wise axis, the portion of the optical fiber that is received in the groove formed in the top ferrule portion is disposed within the groove such that the optical axis of the portion of the optical fiber is parallel to the length-wise axis of the groove, and the reflector is disposed opposite an end of the groove, wherein light is transmitted between the reflector and the optoelectronic device without relying on any refractive optical element supported on the optical fiber alignment assembly, and a hermetic sealant hermetically attaching the top ferrule portion to the bottom ferrule potion and hermetically sealing a space around a section of the optical fiber between the top ferrule portion and the bottom ferrule portion.
