High Spectral Efficiency Coherent Optical OFDMDM (CO-OFDM) takes advantage of software capabilities of electronic digital signal processing (DSP) to perform sophisticated operations and has demonstrated its easiness of realizing high spectral efficiency and combating various distortions at the same time. This chapter presents the signal process

Polarization-Division-Multiplexed Coherent Optical OFDM Transmission Enabled by MIMO Processingaul transmission systems is discussed. Polarization de-multiplexing of the PDM signal at the receiver is realized with a multiple input multiple output (MIMO) processing. With the help of PDM, continuously detectable transmission is reported of 10 × 121.9?Gb/s (112.6?Gb/s without OFDM overhead) at 5

No-Guard-Interval Coherent Optical OFDM with Frequency Domain Equalizationtical transport network (OTN). Unlike the conventional OFDM configuration, the proposed scheme employs a very small number of OFDM subcarriers, so simple optical analog subcarrier multiplexing can be realized without digital signal processing (DSP) in the OFDM modulation. The scheme also introduces

QPSK-Based Transmission System: Trade-Offs Between Linear and Nonlinear Impairmentsnonlinear impairments. Several variants of QPSK-based format implementations including non-coherent RZ-DQPSK, coherent SP-QPSK, and coherent DP-QPSK will be introduced and discussed from a viewpoint of trade-off between nonlinear and linear tolerances.

Integrated Mach–Zehnder Interferometer-Based Modulators for Advanced Modulation Formatsecisely. By using a pair of Mach–Zehnder interferometers, the real and imaginary components of the lightwave can be manipulated independently. This technique is called vector modulation, which is commonly used in wireless radio communication systems. As well known, lightwave state can be mathematica
