Abstract
By using novel stabilizing and control technique of bit-wise phase correlation based on 1-bit delay interferometers, we demonstrated stable generation of bitwisely phase-controlled 160-Gb/s signals with different modulation formats such as carrier-suppressed return-to-zero (CS-RZ), pair-alternate-phase CS-RZ (PAP-CSRZ), π/2-altenate-phase RZ (π/2- APRZ), and periodical APRZ. Furthermore, novel performance monitoring technique for 160 Gbit/s OTDM signal using an asynchronous electro-absorption modulator (EAM) prescaler is proposed. This performance monitor can detect waveform distortion caused by chromatic dispersion, polarization mode dispersion (PMD) and optical signal-to-noise ratio (OSNR) degradation separately. And the feasibility of the monitor was examined by an optical test-bed in JGNII network.
