Claim:
1. An optical engine for data communication comprising: (a) a substrate defining a longitudinal axis; (b) an array of optical semiconductor devices transversely mounted on the substrate, the optical semiconductor devices being selected from the group consisting of transmitting optoelectronic components, receiving optoelectronic components and a combination thereof; (c) a device lens block mounted on the substrate and formed with a cavity for accommodating therein the array of optical semiconductor devices, wherein two device lens arrays are formed on two opposite sides of the device lens block respectively; (d) a jumper lens block coupled with the device lens block at an upper surface thereof, wherein the jumper lens block is formed with a first alignment portion configured to snugly engage with a second alignment portion formed on the device lens block so as to facilitate precise optical alignment of the jumper lens block with the device lens block, and a lens array formed on a total internal reflective surface disposed at an angle of 45 degrees with respect to the substrate; (e) a fiber array mounted on the jumper lens block and optically coupled with the array of optical semiconductor devices via one of the device lens arrays of the device lens block and the lens array of the jumper lens block; and (f) a metal latch for holding the jumper lens block in a fixed position on the device lens block, wherein the metal latch comprises a first portion detachably coupled with the device lens block and a second portion contacting and biasing the jumper lens block against the device lens block; wherein the second alignment portion is in the form of two pairs of alignment notches formed on two opposite sides of the device lens block respectively, each pair of alignment notches being used to receive therein the first alignment portion of the jumper lens block which is in the form of a pair of alignment posts formed on the jumper lens block.
