Photonic integrated circuits for next-generation computing (optical neural network, data centers, hyper-scale computing)

The advent of parallel computing paradigm that requires large bandwidth has created a need for integrating high performance photonic systems with electronics. Also, new computing fields where photonics can play unique roles are emerging such as optical neural network and hyperscale computing. In our group, we are developing scalable and power-efficient photonic integrated circuits such as silicon photonic switches, tunable directional couplers, and optical phase shifters.
