"send and retrieve data to maximize information density—several signals on different wavelengths are sent simultaneously for parallel processing which increases the detection speed of recognition tasks. Each wavelength increases the computational speed. The device naturally captures similarities in datasets while doing so in parallel using light to increase the overall computation speed—which can far exceed the capabilities of conventional electronic chips"
