Abstract
A light receiving and emitting module includes a sub-mount platform, a photoelectrical conversion component, a lens and a base. The sub-mount platform is made of silicon-based material and has first and second contact surfaces. The photoelectrical conversion component is disposed on the first contact surface. The lens is disposed on the second contact surface. The sub-mount platform is disposed on one side of the base. The first contact surface and second contact surface have therebetween a height difference, such that the photoelectrical conversion component matches the center of the lens. Further provided is a light receiving and emitting device including the light receiving and emitting module, a printed circuit board and a plurality of conducting wires. The conducting wires are electrically connected to the photoelectrical conversion component and printed circuit board. The conducting wires are disposed on at least two sides of the light receiving and emitting module.
