Abstract
A simple and efficient board-to-board optical interconnection consisting of a laser, two lenses and a detector is constructed, which demonstrates the direct free-space interconnection of GaAs digital circuits. The link is operated at clock rates up to 1 GHz, and no external laser driver, detector preamplifier or other interface circuitry is required because of the high efficiency of the interconnection. A differential electrical-to-electrical current efficiency is measured as high as 19 percent. The use of prealigned optical modules promises increased tolerance to misalignments.
