Abstract
Optical communication devices and optical communication methods are described. The devices and methods may be implemented in parallel optical communication applications according to some exemplary described aspects to provide enhanced bandwidth. According to one aspect, an exemplary optical communication device includes a plurality of light sources configured in an array and individually adapted to communicate information with respect to an optical communication medium. Individual ones of the light sources are configured to emit light having at least three different and distinct levels to communicate the information with respect to the optical communication medium. The device of this aspect further includes a controller configured to provide a plurality of control signals to control respective ones of the light sources to individually communicate respective information using the at least three different and distinct levels to implement multi-level coding. Other aspects are described.
