A High Sensitivity Temperature Sensing Probe Based on Microfiber Fabry-Perot Interference

open access: yesItalian National Conference on Sensors, 2019
In this paper, a miniature Fabry-Perot temperature probe was designed by using polydimethylsiloxane (PDMS) to encapsulate a microfiber in one cut of hollow core fiber (HCF). The microfiber tip and a common single mode fiber (SMF) end were used as the two

A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...

Demonstration of 3-port grating phase relations

open access: yes, 2006
We experimentally demonstrate the phase relations of 3-port gratings by investigating 3-port coupled Fabry-Perot cavities. Two different gratings which have the same 1st order diffraction efficiency but differ substantially in their 2nd order diffraction

Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

open access: yesAdvanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

3D Microprinting of Structures with Lanthanide‐Based Fluorophores on Optical Fibers for Multiplexed Sensing

open access: yesAdvanced Optical Materials, EarlyView.
Incorporating lanthanide‐based fluorophores into commercial resists for femtosecond direct laser writing enables a novel platform for multiplexed sensing. Porous, periodic, and solid luminescent microstructures fabricated directly on optical fiber tips are presented.

Infrared Colloidal Quantum Dot Edge Emitting Lasers Integrated on Silicon

open access: yesAdvanced Optical Materials, EarlyView.
In this work, the first monolithic integration of Pb‐chalcogenide CQDs in an edge‐emitting DFB laser cavity onto a Si/SiO2 substrate has been demonstrated. The optimizations of SiO2 layer thickness, engineering of the grating duty cycle, and implementing λ/4 phase shift resulted in the achievement of spectrally pure, single‐mode lasing at 1650 nm with ...

Enhancing the modulation depth of a dynamic terahertz metasurface by integrating into an asymmetric Fabry-Pérot cavity

open access: yesAIP Advances, 2018
The modulation capability of a terahertz dynamic metasurface was enhanced by integrating it with an asymmetric Fabry-Pérot cavity. The dynamic metasurface consists of split ring resonators combined with high frequency metal semiconductor metal varactors.
