TL;DR: A silicon-polymer hybrid modulator that maintains high data rates for long periods at high temperatures that could be used under such conditions, to reduce energy consumption is introduced.
Wavelength conversion of optical 64QAM through FWM in HNLF and its performance optimization by constellation monitoring.
TL;DR: The experimental results show that, constellation monitoring provides a more intuitive and accurate approach to monitor the converted high-order QAM signals, especially in presence of nonlinear phase noise such as self-phase modulation (SPM).

Flexible high-order QAM transmitter using tandem IQ modulators for generating 16/32/36/64-QAM with balanced complexity in electronics and optics.
TL;DR: A flexible high-order QAM transmitter using a tandem in-phase/quadrature (IQ) modulators to synthesize different high- order quadrature amplitude modulation (QAM) formats, such as 16QAM, 32 or 36QAM and 64QAM is proposed.
