   The Modulating RetroReflector (MRR) system has been demonstrated to provide continuous asymmetric free space optical communication at data rates up to 200 kbps* using a binary modulation scheme. The MRR subcomponent is housed in a compact, easy-to-integrate package geared for laboratory technology demonstration. This technology can be used out of the box or integrated into a complete setup through the use of standard optical components. The MRR can be paired with the MB-200 Driver to enable immediate testing of an optical protocol using a standard TTL input. See below for complete device specifications.

*Higher data rates are in development

MEMS Modulating Retroreflector

Low Power Modulating RetroReflector (MRR) for Free Space Optical Communication

When mounted as one facet of a hollow corner cube retroreflector, the Boston Micromachines Broadband Optical Modulator is capable of passively returning light from an interrogating laser source and modulating its intensity for asymmetric communication.  In its unpowered state the MRR acts as a typical retroreflector, returning a high percentage of light to the source. In its powered state, most of this light is scattered.
