Abstract
Photonic processors are described herein that are configured to perform matrix-matrix (e.g., matrix-vector) multiplication by directly encoding a first value in the output of the light source. Some embodiments relate to a photonic device configured to perform a mathematical operation, the photonic device comprising a modulatable light emitting diode (LED) and a modulatable detector. The modulatable LED being configured to emit light. The modulatable detector being optically coupled to an output of the modulatable LED. The photonic device further comprising, a controller being configured to encode a first value in the light emitted by the modulatable LED and to encode a second value in a characteristic of the modulatable detector; and a receiver configured to determine a result of the mathematical operation based on an electrical signal produced by the modulatable detector.
