Abrégé

Embodiments disclosed herein address these and other issues by providing a retro-modulating optical "tag" with a wide FOV that enables high-speed communication in a compact design. Embodiments enable retro-modulation via a lens assembly that directs light to a reflective surface, through a Quantum Well Modulator (QWM) that modulates the light. A wide field of view can be achievable, for example, using a lens with a high index of refraction, which may be optically contacted with the QWM.
