ABSTRACT:
To provide a microoptical system for free-space optical interconnection capable of relaxing the arrangement accuracy of a light source and a photodetector. A point light source and a photodetector are interconnected each other by first and second imaging lenses and focused Gaussian beams. In this case, the point light source, first imaging lens, second imaging lens, and photodetector are positioned so that the effective beam radius .omega..sub.2 of a focused Gaussian beam on the first interconnecting lens is larger than the effective beam radius .omega..sub.4 of a focused Gaussian beam on the second imaging lens.
