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.

Polarization‐dependent gain characterization in x‐cut LNOI erbium‐doped waveguide amplifiers

Nanophotonics, Volume 14, Issue 27, Page 5081-5094, December 2025.
Abstract Erbium‐doped waveguide amplifiers (EDWAs) are vital for photonic integration, yet most are built on z‐cut lithium niobate, incompatible with the mainstream x‐cut platform. This work presents a combined theoretical and experimental study of polarization‐dependent gain in x‐cut Er:LNOI. Using Judd–Ofelt theory, we analyze how crystal orientation
