"digital data encoded into light waves' amplitude/ phase, turning numbers into optical fields' physical properties... deep learning matrix/ tensor multiplications occur naturally as light fields interact/ combine... passive, requiring no active control/ electronic switching... using multiple wavelengths enables handling higher-order tensor operations... connects input to correct output instantly... integration with existing photonics hardware within 3 to 5 years... optical computing for fast, low power consumption, complex AI"
