Inverse‐Designed Silicon Nitride Bimodal Mode Converter for Interferometric Sensors

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Inverse‐designed bimodal mode converters are demonstrated on two silicon nitride platforms. The devices convert the fundamental mode into near‐balanced pairs of the fundamental and higher‐order modes up to the third order. They are compact and fabrication‐tolerant. Characterization of a bimodal interferometer incorporating these converters demonstrates

Ultra‐Low Loss Weakly Coupled Few‐Mode Hollow‐Core Anti‐Resonant Fiber Enabling Eight Channels via Differential Wall Thickness and Truncated Tubes

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A novel ultra‐low loss, weakly coupled few‐mode hollow‐core anti‐resonant fiber is realized through truncated tubes and differential wall thickness, which can support eight spatial modes as independent channels. The effective refractive index difference between adjacent modes is greater than 1.0 × 10−4, and the intrinsic loss of all target modes at ...

Age‐Associated Senescence of Decidual Macrophages: A Key Mediator of Adverse Pregnancy Outcomes in Advanced Maternal Age

Aging Cell, Volume 25, Issue 7, July 2026.
Decidual macrophages (DM) in advanced maternal age (AMA) exhibit FOXO3 deficiency‐driven senescence, further accelerated by elevated uterine IL‐6. This manifests as pro‐inflammatory polarization, increased senescence markers, reduced phagocytosis, and impaired trophoblast function.

Mode and Polarization Division Multiplexing Based on Chalcogenide‐Glass‐on‐Thin‐Film Lithium Niobate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
High‐index GeSbSe chalcogenide glass loaded on thin‐film lithium niobate enables compact broadband mode‐ and polarization‐division multiplexing. Exploiting direction‐dependent birefringence of x‐cut LNOI, a four‐channel mode (de)multiplexer and asymmetric directional coupler‐based polarization splitter–rotator are demonstrated with great performance in
