Reconfigurable microwave photonic filter based on tunable dispersion-induced power fading in a dispersive element
TL;DR: In this article, a reconfigurable microwave photonic filter (MPF) based on tunable dispersion-induced power fading (DIPF) in a dispersive element is presented.
Journal ArticleDOI
Reconfigurable microwave signal processor with a phase shift of π.
TL;DR: A reconfigurable microwave signal processor, with a bandwidth up to tens of gigahertz, and the frequency response of the approach could be in a great agreement with that of an ideal signal processing function.

TL;DR: In this article, the frequency and temporal coherence properties of a distributed Bragg reflector laser were investigated, where a square-wave from voltage is applied to the phase section of the laser to little optical wavelength, and delayed optical heterodyne technique is used for the analysis of spectral characteristics.
Journal ArticleDOI
Frequency response of fiber ring resonator and its application in dfb laser wavelength variation measurement
TL;DR: In this article, the frequency response of a fiber ring resonator (FRR) composed of an ordinary optical coupler and a segment of optical fiber is derived and studied in detail.
Proceedings ArticleDOI
Performance Enhancement of 112 Gb/s PAM-4 Amplifier-Free 40km Transmission with Record Sensitivity using O-Band 25G-Class Directly Modulated Laser
TL;DR: An amplifier-less transmission of a single-wavelength 112Gb/s PAM4 signal over 40km using O-band 25G class DML and advanced DSP with a record receiver sensitivity of − 12dBm@HD-FEC is experimentally demonstrated.
