Tunable, High Pulse Energy and Narrow Linewidth Gas‐Filled Fiber Laser Across Near‐ and Mid‐Infrared

Laser &Photonics Reviews, EarlyView.
A cascaded gas‐filled anti‐resonant hollow‐core fiber architecture enables broadly tunable infrared Raman lasers spanning ∼1.4–4.6 µm while maintaining microjoule‐level pulse energies and gigahertz‐level linewidths. The approach combines a wavelength‐tunable pump laser with optimized Raman frequency conversion, providing a compact route to high ...

Classification of quantum states of light using random measurements through a multimode fiber

Physical Review Research
Extracting meaningful information about unknown quantum states without performing a full tomography is an important task. Low-dimensional projections and random measurements can provide such insight but typically require careful crafting.

Multifunctionality in Silicon Photonics Through Temperature‐Driven Inverse Design

Laser &Photonics Reviews, EarlyView.
Temperature‐conditioned inverse design embeds thermo‐optic reconfigurability directly into compact silicon photonic devices. By co‐optimizing a single geometry at 300 K (T1) and 520 K (T2), the same structure supports distinct optical functions, enabling experimentally verified switching and mode conversion without resonant architectures or additional ...

Theory of transverse mode instability in fiber amplifiers with multimode excitations

APL Photonics
Transverse Mode Instability (TMI) that results from dynamic nonlinear thermo-optical scattering is the primary limitation to power scaling in high-power fiber lasers and amplifiers.

High‐Speed Integrated Graphene‐Silicon Slot‐Waveguide Electro‐Absorption Modulator at 2 and 1.5 µm Wavebands

Laser &Photonics Reviews, EarlyView.
A high‐speed, efficient, robust, and compact 2‐μm$\mathrm{\mu}\mathrm{m}$ waveband E/O absorption modulator based on a graphene‐silicon slot waveguide is demonstrated. This work represents a significant advancement towards the realization of high‐speed integrated E/O modulators for optical communication systems operating at the 2‐μm$\mathrm{\mu}\mathrm{

Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.
