Optical transmitter tunable over a 65-nm wavelength range around
The transmitter is able to produce phase-controlled optical pulses at GHz speeds with a tunable wavelength range of centered at 1550 nm. With this transmitter, we perform proof-of-principle

Optical fibers serve as the foundation of an optical transmission system because they transport optical signals from source to destination. The combination of low-loss and large bandwidth allows high
End-to-end Optimization of Optical Communication Systems
The present work aims to jointly optimize transmitter GCS and LPS and receiver EQ with the driving configuration of the DML (Ibias, Ipp), thus tailoring E2E learning to the specific
Optical Digital‐To‐Analog Converters (oDACs): A Solution to
This article aims to thoroughly examine the limitations of traditional transceivers and present our latest research findings on transmitters utilising optical digital-to-analog converters (oDAC).
A 40Gb/s PAM4 Transmitter based on a Ring-resonator Optical DAC
In this work, we demonstrate the capability of implementing high-speed optical trans- mitters meeting the needs of data centers for 100G=400GEthernet in the same platform, with ultra-low power
Optical Transmitters without Driver Amplifiers—Optimal
Conversely, digital post-distortion provides operation with larger eye-openings, and therefore, provides an SNR increase of at least 0.5 dB. Furthermore, we find that increasing the roll-off factor increases
A fast 100-channel wavelength-tunable transmitter for optical
In summary, we have demonstrated a fast and precise 100-channel wavelength-tunable transmitter, which is suitable for optical packet switching. The wavelength switching perfor-mance has been
A Robust Adaptive Pre-Distortion Method for Optical Communication
In this letter, we propose a new robust pre-distortion method to mitigate the undesirable linear and non-linear distortions of all electrical and optical transmitter components simultaneously. A
