Phase noise characterization of injection locked semiconductor lasers to a 250 MHz optical frequency comb

Two lasers are simultaneously injection locked to the same comb mode and the injection locking quality is assessed in terms of phase noise and phase variance (1 kHz-10 MHz) for various injected ...

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

Laser &Photonics Reviews, EarlyView.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Epitaxial Integration of III–V Membrane Photodetectors With Lateral p–i–n Junctions on the Silicon‐On‐Insulator Waveguide Platform

Laser &Photonics Reviews, EarlyView.
Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

Simultaneous low noise radio frequency tone and narrow linewidth optical comb generation from a regeneratively mode-locked laser

, 2014
A regeneratively mode-locked laser with simultaneous low noise radio frequency (RF) tone and optical comb generation is presented. The laser does not need any external RF signal and emits a pulse train at similar to 10 GHz repetition rate with a 1.5-ps ...

Review on Processing Control Strategy for Electrochemical Additive Manufacturing

MetalMat, EarlyView.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...
