Mitigation of Nonlinear Impairments by Using Support Vector Machine and Nonlinear Volterra Equalizer
Applied Sciences, 2019 A support vector machine (SVM) based detection is applied to different equalization schemes for a data center interconnect link using coherent 64 GBd 64-QAM over 100 km standard single mode fiber (SSMF).

DP-QPSK Coherent Detection Using 2D Grating Coupled Silicon Based Receiver
IEEE Photonics Journal, 2021 We propose and demonstrate a 100 Gbit/s silicon photonic (SiPh) coherent receiver (Rx) with advanced digital signal processing (DSP) for dual-polarization quadrature-phase-shift-keying (DP-QPSK) transmission.

The microbiome in human skin aging
FEBS Letters, EarlyView.Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

On the Average Achievable Rate of QPSK and DQPSK OFDM Over Rapidly Fading Channels
IEEE Access, 2018 Motivated by recent experimental observations, where differentially coherent detection outperforms coherent detection on certain underwater acoustic channels, we revisit the performance of these two methods with respect to the achievable rate in ...

Simple Noise Mitigation Scheme for Coherent Optical DMT Signal Transmission System
IEEE Access, 2020 We propose and experimentally demonstrate a noise mitigation scheme for coherent optical discrete multitone (DMT) signal transmission system. The proposed scheme can mitigate the laser phase noise and additive white Gaussian noise (AWGN) simultaneously ...

Four-in-one interferometer for coherent and self-coherent detection
Optics Express, 2013 A compact micro-optical interferometer is presented that combines two optical 90° hybrids or, alternatively, four delay interferometers into one interferometer structure sharing one tunable delay line. The interferometer can function as a frontend of either a coherent receiver or of a self-coherent receiver by adjusting the waveplates and the delay ...
