The problem is efficiency. Maxwell's equations are completely linear, so nonlinear optics relies entirely on materials with nonlinear response to optical fields. Unfortunately these responses deviate ...

When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses. These physical phenomena are ...

A photonic image/video/vision recognition system would be a huge step forward for autonomous moving systems. Your robot car could see and categorize a potentially dangerous object up ahead in ...
