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...
This investigation proposes and experimentally demonstrates an optical code-division multiple-access (OCDMA) light source using a directly modulated Fabry–Pérot laser diode in an external injection sc...
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...
We generate the QPSK signal by utilizing the chirp characteristics of the directly modulated RSOA for the high-speed coherent WDM PON. In addition, we demonstrate the error-free transmission of the 5-...
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...
A simple, highly-effective, DSP-free, optical OFDM(OOFDM) synchronous clock recovery technique preserving system performance and enhancing stability is proposed and experimentally demonstrated, for th...
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...
By employing optical injection-locking the direct modulation bandwidth of a 10μm diameter disc laser is increased to 15GHz. In addition, modulation at 20Gb/s is demonstrated with only 1mW DC bias & 19...
We demonstrate a 10-Gbit/s transmission over a 5-km photonic crystal fiber in the 1.1 μm band using a directly-modulated single-mode VCSEL. The transmission distance was extended to 14 km by using an ...
We demonstrate the error-free transmission of 11-Gb/s 4-ary PAM signal obtained by using a directly modulated RSOA over 20 km of SMF for the cost-effective realization of high-speed WDM PONs.
We experimentally investigate the use of various line coding schemes (8B/10B, 5B/6B,7B/8B, 9B/10B, 64B/66B) to improve the performance of frequency modulation-based directly modulated lasers. We show ...
We implement a cost efficient 10.7Gb/s directly modulated DPSK transmitter in a bidirectional WDM-PON, which also remodulates the downstream phase encoded signal for 2.5Gb/s OOK upstream transmission.
A simultaneous extinction-ratio enhancement and frequency stabilization scheme is proposed for directly modulated DFB lasers at the optical line terminal to enhance signal quality and to stabilize opt...
Filtering of the chirped signal from a directly modulated laser with the narrowband optical filter with a high roll-off allows to in-crease the dispersion tolerance of the transmitter substantially. ...
10Gbit/s self thermally compensated directly modulated laser with electronic dispersion compensation is proposed to achieve 20km reach with 28 or 25dB optical budget between 5° C and 60 or 80° C respe...
