Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Integration of III‐V Quantum Dot Photonic Devices on Silicon Nitride via Lithography‐Aligned Micro‐Transfer Printing

Laser &Photonics Reviews, EarlyView.
Lithography‐aligned micro‐transfer printing integrates unprocessed InAs/GaAs quantum dot membranes with silicon nitride photonic circuits. Post‐transfer patterning defines quantum dot photonic devices directly on the target chip, enabling precise GaAs–SiNx coupling, purcell‐enhanced single photon emission, and scalable on‐chip routing and correlation ...

Stark‐Tunable O‐Band Single‐Photon Sources Based on Deterministically Fabricated Quantum Dot ‐ Circular Bragg Gratings on Silicon

Laser &Photonics Reviews, EarlyView.
Electrically contacted circular Bragg grating resonators incorporating InGaAs quantum dots directly grown on silicon enable bright, telecom O‐band single‐photon emission with wide‐range electrical tuning. A record quantum‐confined Stark shift of 16 nm is combined with high photon extraction efficiency, excellent single‐photon purity > 99.9%, and robust

Structural Brain and Spinal Cord Signature of Spinocerebellar Ataxia 27B: A Multisite MRI‐Based Study

Movement Disorders, EarlyView.
Abstract Background SCA27B is a recently described ataxia, the precise anatomical basis of which remains unclear. Objective The goal was to characterize the structural brain and spinal cord magnetic resonance imaging (MRI) signature of spinocerebellar ataxia 27B (SCA27B) using multimodal quantitative imaging.
