An optical time-and-wavelength-division-multiplexing metro-access network (TWDM-MAN) is proposed and demonstrated in this paper. By the reuse of tangent-ring optical distribution network and the design of distributed control mechanism, ONUs needing to communicate with each other can be flexibly accessed to successfully make up three kinds of reconfigurable networks. By the nature advantage of ring...
This paper presents a dual-cavity mode-locked laser, which is able to simultaneously output two optical pulses with different wavelengths and frequency. In this dual-cavity configuration, one cavity works as a regenerative mode-locked laser and outputs signal with a fundamental repetition frequency, the other one acts as an active mode-locked laser and generates signal with subharmonic or harmonic...
