Effectiveness of E‐Learning in Undergraduate ENT Education: A Mixed‐Methods Systematic Review

open access: yesThe Laryngoscope, EarlyView.
E‐learning in undergraduate ear, nose, and throat education was evaluated in a mixed‐methods systematic review of 29 studies. Pooled analysis showed a modest knowledge gain of 26.8%, variable effects on skills, and consistent improvements in learner confidence. These findings support e‐learning as a useful adjunct, rather than a standalone replacement,

Ultra‐Compact Broadband Spot Size Converter Using Metamaterial Cell‐Based Inverse Design

open access: yesLaser &Photonics Reviews, EarlyView.
Inverse design techniques are combined with subwavelength structures to design a compact, high‐performance spot size converter. A cell‐based topology is proposed, where each cell is composed of an equivalent homogenous metamaterial, resulting in a reduced parameter that speeds up optimization. A 7 μm$\mu{\rm m}$‐long device that achieves a 24‐fold beam

A Scalable Quadratic Nonlinear Silicon Photonics Platform With Printable Entangled Photon‐Pair Sources

open access: yesLaser &Photonics Reviews, EarlyView.
A scalable quadratic nonlinear photonic platform is demonstrated by heterogeneously integrating periodically poled lithium niobate with silicon photonics. Relying on the superior CMOS fabrication tolerances, reproducible and deterministic phase‐matching is achieved.
