Abstract :
We describe a telecentric optical system for free-space multichannel optical interconnects. The targeted aggregate data rate is 240 Gb/s. We have a unique implementation of telecentric optics and achieved an optical link that is simple, robust and modular. The integrity of the optical link is not significantly degraded with a >plusmn2 mm translational misalignment between the transmitter and receiver arrays. With this optical link, we need only a low bandwidth active servo mechanism to compensate for static tilt and possibly low frequency thermally-driven shift between the transmitter and receiver arrays.
