We present a simultaneous radio-frequency (RF) and high-speed baseband signal transmission using an electrically superimposed method over a graded-index silica multimode fiber (GI-MMF). To show the feasibility of the method, we experimentally demonst

We demonstrate all-optical wavelength conversion of a 4-level pulse-amplitude modulation (PAM-4) signal by cross gain modulation (XGM) in a quantum-dot semiconductor optical amplifier (QD-SOA). In this scheme, the center passband of a conventional op

We propose a photonic digital-to-analog conversion (DAC) based on frequency chirp using a quantum-dot semiconductor optical amplifier and following blue-shift filtering. We experimentally demonstrate 10-Gbps all-optical binary-to-quaternary conversio

We have experimentally demonstrated all-optical wavelength conversion of PAM-4 signals based on cross gain modulation in a quantum-dot semiconductor optical amplifier. As a result, we have successfully achieved 5-nm regenerative wavelength conversion
