Design of a Tapered Slot Waveguide Dielectric Laser Accelerator for Sub-Relativistic Electrons

Conference on Lasers and Electro-Optics, 2018
We design and analyze a tapered slot waveguide structure for sub-relativistic electron acceleration. The tapering scheme can be designed, through the eikonal approximation’ to achieve phase synchronization with the accelerated electrons.

Photonic Crystal Fibers in the Terahertz Regime: Design Strategies, Performance Metrics, and Emerging Applications: A Systematic Review

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
An optimized octagonal‐core terahertz (THz) photonic crystal fiber sensor is presented for accurate identification of different milk samples based on refractive index variation. The structure enables highly confined THz guidance and strong light–analyte interaction, allowing reliable discrimination of camel, cow, buffalo, and sheep milk.

High‐Performance All‐Optical Modulator Based on Graphene‐Loaded Ultrathin Silicon Slot Waveguides

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
A novel scheme composed of graphene‐loaded ultrathin silicon slot waveguide is demonstrated realizing high‐performance all‐optical modulation on silicon photonic platform. Owing to the enhanced light–matter interaction and suppression of two‐photon absorption, the device shows a measured modulation depth over 3dB, a modulation efficiency of 0.086 dB/μm

Enhancement and Speed‐Up of Carrier Dynamics in A Dielectric Nanocavity with Deep Sub‐Wavelength Confinement

Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
This work presents the first experimental investigation of ultrafast dynamics in dielectric bowtie nanocavities, featuring deep‐subwavelength mode confinement. Measurements reveal enhanced two‐photon absorption, sub‐picosecond carrier relaxation, and strong pump–probe interactions, demonstrating clear advantages over conventional nanocavities for low ...
