WebJan 29, 2024 · In this paper, we demonstrate a narrow-linewidth tunable fiber laser based on laser-induced graphene (LIG) paper-heated fiber Bragg grating (FBG) with low voltage. A linewidth of less than 600 Hz is achieved by the combination of a piece of unpumped Er-doped fiber and an FBG. Changing the temperature of the FBG will result in the central … WebJun 14, 2024 · For the transmitter chip, a pulse-modulated 1542.3815-nm frequency-locked laser is coupled into the silicon waveguide through a grating coupler. The first Mach-Zehnder interferometer (MZI) modulator modifies the laser intensity to create signal and decoy states, and another phase modulator implements random phase modulations of …
