The investigation of the nonlinear dynamics of a semiconductor laser based on nonlinear optical loop mirror (NOLM) feedback using Ge doped optical fiber was carried out experimentally. Animations of c...
Transmission of Multi-Band OFDM-UWB Signals along NG-FTTH Networks using Directly Modulated Lasers
Modulation Optical communications
2015/5/26
Transmission of multi-band OFDM-UWB signals along FTTH networks using directly modulated lasers is experimentally evaluated. Reach of 100 km of standard SMF is achieved with a BER below 10 -4 and an O...
Generation of 20-Gb/s RZ-DQPSK Signal using a Directly Modulated Chirp Managed Laser
Generation RZ-DQPSK Signal Directly Modulated Chirp Managed Laser
2015/5/21
We generate 20-Gb/s return-to-zero differential quadrature phase-shift-keying (RZ-DQPSK) signal using a directly modulated chirp managed laser (CML), without requiring any differential encoder and opt...
Demonstration of 25.78-Gb/s, 20-km Reach WDM PON Using Directly-Modulated Bandwidth-Limited RSOA
Fiber optics links subsystems Semiconductor optical amplifiers
2015/5/20
We demonstrate the 25.78-Gb/s operation of directly-modulated RSOA. The results show that it is possible to transmit the 25.78-Gb/s signal over 20 km in the wavelength range of ~20 nm with the dispers...
50 fJ-per-bit, High Speed, Directly Modulated Light Sources for On-chip Optical Data Communications
