In a collaboration with the High Voltage Laboratory at the department of Information Technology and Electrical Engineering (D-ITET), we have used our photonic integrated circuits to optically measure electric field strengths.
We realized a device that modulates the signal in the C-band and generates the second harmonic, obtaining a signal in the visible with double extinction ratio.
Nonlinearity is essential for neural networks but extremely challenging to implement with light. Here, we demonstrate how a nonlinear disordered material can enhance the performance of state-of-the-art photonic neuromorphic computing.
