Nonlinear Dynamics in Directly Modulated Semiconductor Lasers with Optical Loop Mirror Feedback
Nonlinear Dynamics Nonlinear Loop Mirror Pulse Multiplication Optical Chaotic And Pulse Mode Locking
2012/12/28
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...
On the Interest of Chirped Lasers for AMOOFDM Transmissions in Long Distance PON Networks
Fiber optics communications Modulation
2011/5/26
We report the performance of a chirped laser in IMDD-based transmissions and we show that the interplay between laser chirp and fiber dispersion can be very attractive for long distance PONs if adapti...
Transmission of Multi-Band OFDM-UWB Signals along NG-FTTH Networks using Directly Modulated Lasers
Modulation Optical communications
2011/5/26
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...
Demonstration of Low-Cost Uplink Transmission in a Coherent OCDMA PON Using Gain-Switched Fabry–Perot Lasers With External Injection
Fabry–Perot (FP) laser gain-switching optical code-division multiple access (OCDMA) passive optical network (PON)
2010/12/2
We propose and demonstrate a simple and low-cost uplink transmission scheme for coherent optical code-division multiple access (OCDMA) passive optical networks (PONs), using gain-switched Fabry-Perot ...
