Optical subassembly

An apparatus comprising:

• a semiconductor laser fixed to a board substrate so that the semiconductor laser emits light in a direction substantially perpendicular to the plane of the board substrate, through an opening in the board substrate;
• a base having a first opening of a dimension suitable to pass a light emission therethrough, fixedly attached to the board substrate so that the first opening aligns with the opening in the board substrate through which the semiconductor laser emits light;
• a first side wall coupled to the base and having a second opening of a dimension suitable to pass a light emission therethrough;
• a second side wall coupled to the base and having a planar reflective component thereon, and the base, the first side wall, and the second side wall define an interior chamber with the planar reflective component disposed in the interior chamber;
• and
• a fiber connector adapted to accept an LC connector extending from an exterior of the first side wall adjacent the second opening.
