Laser matrix for optical neural networks

A laser system, comprising:

• one or more pump light sources configured to generate pump light, the pump light comprising a first wavelength;
• one or more injection lasers configured to generate injection light, the injection light comprising a second wavelength that is longer than the first wavelength;
• one or more light modulators configured to selectively modulate the injection light received from the one or more injection lasers to produce input signal light;
• and
• a laser cavity matrix comprising a plurality of laser cavities, wherein each laser cavity of the plurality of laser cavities comprises a laser gain medium and is configured to (i) receive pump light from the one or more pump light sources to cause stimulated emission within the laser gain medium to generate an output laser light and (ii) receive input signal light from the one or more light modulators to cause injection locking of the output laser light, wherein each laser cavity of the plurality of laser cavities is configured to receive the pump light and the input signal light from a same side of the laser cavity matrix.
