22.8-GHz Optical Frequency Comb Generation at 780 nm Based on Regeneratively Mode-Locked Laser for Visible-Light Coherent DWDM Communications
We, for the first time, demonstrate a regeneratively mode-locked laser at 780 nm with a 10-dB bandwidth of 707 GHz. By using the developed laser, a demodulation of 10-Gbaud QPSK signal was achieved.
