SiN-SOI Multilayer Platform for Prospective Applications at 2 μm

IEEE Photonics Journal, 2019
Silicon photonics at the 2 μm waveband, specifically the 1.9 μm wavelength region is strategically imperative. This is due to its infrastructural compatibility (i.e., thulium-doped fiber amplifier, hollow-core photonic bandgap fiber) in ...

Pump‐Probe Imaging of Ultrafast Laser Percussion Drilling of Glass in Single Pulse, MHz‐ and GHz‐Burst Regimes

Advanced Materials Interfaces, EarlyView.
Pump‐probe shadowgraphy of glass drilling is shown with a femtosecond laser operating in MHz‐ and GHz‐burst regime. A comparison with standard femtosecond micro‐processing using repetitive single pulses is provided. The ablation plume lifetime is measured in all three regimes, and the drilling dynamics of Through Glass Via (TGV) in GHz‐burst mode are ...

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Ultracompact TM-Pass Silicon Nanophotonic Waveguide Polarizer and Design

IEEE Photonics Journal, 2010
An ultracompact transverse magnetic (TM)-pass polarizer based on silicon nanophotonic waveguides is proposed, which contains two tapered waveguides sandwiching a narrow waveguide section only supporting TM-mode propagation.

Optofluidics: waveguides and devices

SPIE Proceedings, 2012
In this work we review recent results of our work on optofluidics. We show that single mode optofluidic waveguides with low loss can be realized using antiresonant reflecting optical confinement (ARROW). These waveguides can be fabricated using full standard silicon technology or hybrid silicon-polymer processes.

Multiplexed Bio‐detection on an Interferometric Optical Waveguide Assembly

Advanced Materials Interfaces, EarlyView.
Multiplexed remote bio‐detection is demonstrated through an image conduit composed of 3012 individual cores and coated with interferometric layers. The proof of concept of biodetection is performed through the kinetic monitoring of two complementary DNA strands hybridization paving the way for applications in multiplex in situ biosensing, and ...

Multiplexed Antibody Detection With an Array of Silicon-on-Insulator Microring Resonators

IEEE Photonics Journal, 2009
Optical cavities are considered promising devices for biosensing to satisfy the high demands of the growing proteomics market. We present a prototype sensor for multiplexed label-free monitoring of biomolecular interactions based on an array of three-by ...

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

Advanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...
