Multi Data-Rate Synchronization of 40 GHz Mode-Locked Quantum-Dash Lasers Diodes
Mode-Locked Lasers Diodes Quantum-Dash Multi Data-Rate Synchronization
2015/5/15
Beat-tones at 40-GHz from a QDash-ML laser under 10 to 160 Gb/s optical injection are analyzed. A FWHM linewidth less than 8 Hz is obtained regardless of the rate of injected data stream.
Tunable and variable clock generation up to 1.2 THz by filtering an actively mode-locked 42.5 GHz Quantum Dash Fabry-Perot laser with a reconfigurable filter
