10 Gb/s NRZ

4 channel 100G DQPSK

40 GHz mode-locked laser

Measurement taken on 4 channels of a

dual polarization DQPSK signal, spaced by 50 GHz

Spectral details of the mode-structure of a 40 GHz mode-locked laser. The

real-time update rate supports precise adjustment of the laser cavity.

Two 10 Gb/s channels separated by 50 GHz; Channel 1 being

attenuated by 20 dB. The graph top shows the sum of the two

polarization components, whereas the graph right displays the

polarization components PI and PII separately.
