Self‐Detecting Mid‐Infrared Dual‐Comb Spectroscopy Based on High‐Speed Injection‐Locked Quantum Cascade Lasers

open access: yesAdvanced Photonics Research, EarlyView.
A compact self‐detecting dual‐comb spectroscopy (DCS) system based on dispersion‐engineered, high‐speed packaged quantum cascade lasers (QCLs) at λ≈4.6 μm under coherent injection locking is demonstrated. Broad multiheterodyne comb signal with reduced tooth linewidths by orders of magnitude is recorded.

Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

open access: yesAdvanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications.

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...
