Enhancing FSO‐DWDM Performance Through Compensation Strategies

Engineering Reports, Volume 7, Issue 12, December 2025.
This study investigates the performance of free space optics (FSO) with dense wavelength division multiplexing (DWDM) systems, focusing on the impact of channel number and compensation strategies on bit error rate (BER). Results show that post‐compensation significantly improves performance, extending the system's range from 3 to 5 km.

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.

QCL‐Based Cryogen‐Free THz Optical Wireless Communication Link

Laser &Photonics Reviews, Volume 19, Issue 6, March 18, 2025.
A novel QCL‐based, cryogen‐free, and transportable wireless communication system is presented operating at 2.83 THz. The QCL device is mounted in a compact Stirling refrigerator, while a room‐temperature graphene‐based FET is used as a receiver, implementing a binary on‐off keying (OOK) modulation scheme with Manchester encoding.
