Polarization‐Independent Complex Bragg Grating Filters on Silicon Nitride

Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
This work demonstrates multi‐band polarization‐insensitive optical filters on the 400‐nm thick silicon nitride platform, complying with the LAN‐WDM standard. The filters are based on cladding‐modulated Bragg gratings with judiciously designed grating dimensions.

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.

Indigenous Nigerian Vegetables Harbour Plant Species‐Specific Seed Microbial Signatures for Bacteria and Fungi

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Introduction The seed microbiome is essential for plant health, development, and adaptation. Little is known regarding the constituents of seed microbiomes of Africa's indigenous vegetables, which enables the vertical transmission of a specific microbial heritage. Shedding light on this was the focus of the current study.
