An optical subassembly comprises a two-dimensional semiconductor laser array having a plurality of laser diodes arranged in rows and columns. The laser diodes are configured to provide laser lights at a first and a second direction. A first lenslet module is disposed adjacent the semiconductor laser array, such that light emitted from the laser array in the first direction is collected by the lenslet module. The lenslet module is further configured to focus the collected light at a given first focal point that may be disposed on a receiving end of a fiber optic. A second lenslet module is disposed adjacent the semiconductor laser array, such that light emitted from the laser array in the second direction is collected by the second lenslet module. The second lenslet module is further configured to focus said collected light at a given second focal point disposed at the receiving end of a photodetector.
