FLEXIBLE HIGH-ORDER QAM TRANSMITTERS FOR ELASTIC OPTICAL NETWORKS

摘要：

　　In order to adapt to the dynamics in the future optical networks,we propose and experimentally two flexible high-order quadrature amplitude modulation(QAM)transmitter schemes: i)a flexible transmitter using a tandem in-phase/quadrature(IQ)modulators for generating 16-/32-/64-QAM signals; and ii)a scheme based on monolithically-integrated quad Mach-Zehnder in-phase/quadrature(QMZ-IQ)with binary driving electronics for synthesizing minimum phase-shift keying(MSK),quadrature phase-shift keying(QPSK),8-ary phase shift keying(8PSK),and 16QAM.The flexibility and re-configurability of the proposed schemes are experimentally verified.
