Constellation diagrams of the electric field of optical sources are directly measured using linear optical sampling.
Nonlinearity induced phase noise has become a major obstacle in long-haul coherent fiber-optic communication systems. It has been shown to be signal dependent and hence correlated over time.
We show experimentally that the optical nonlinearities due to intersubband transitions in GaN quantum wells can have both signs, depending on the structure of choice.
The confinement of electron-hole pairs in ultrathin semiconductor layers produces quantum size effects that modify drastically the excitonic behavior as compared to that of the bulk parent material
In this paper, we extend our conference contribution, where we presented a linear-to-nonlinear power ratio monitor based on a shallow artificial neural network and the optical power spectrum.

We present magneto-transmission and emission spectra of n-type multiple quantum wells (MQWs).
Orthogonal frequency-division multiplexing (OFDM) is a widely used modulation/multiplexing technology in wireless and data communications.
Optical OFDM systems are investigated for application at 100 Gb/s bitrate. First the spectral efficiency (SE) of O-OFDM signals is derived including the overheads required for signal reception.
