We demonstrate a multi-channel feedback control for microring weight banks and achieve a record-high accuracy and precision. With the simplified procedures, the feedback control becomes more practical for configuring large-scale photonic networks.

We introduce a hybrid quantum-classical variational algorithms to realize quasi-ML decision of high-dimensional modulation (HDM) in fiber-optic communications, motivated by the recent advancement of quantum processors. Our Ising Hamiltonian model for demodulation is demonstrated on a real quantum processor.

An FWM-based coherent self-superposition technique is proposed and demonstrated to synthesize 12.5-Gb/s SSB Nyquist 16QAM from Twin-SSB Nyquist QPSK, which effectively relaxes DAC resolution requirement. An equalization algorithm is also proposed for such approach's detection.

Using a Correlation-OTDR and a modulation phase shift method we characterized four multi-core fibers. The results show that the differential delay depends on the position of the core in the fiber and varies with temperature.
