Sweeping the infrared with black phosphorus
The band gap of black phosphorus depends strongly on the number of layers and covers wavelengths from 720 to 4000 nm from monolayer to bulk, but only in discrete steps and suffering from poor photostability. In our recent Optical Materials Express, we demonstrate tunable and stable infrared emission from defect states in few-layer BP. First,…
Silicon surface lattice resonances
In collaboration with the group of Jaime Gómez Rivas, we have recently reported surface lattice resonances in arrays of silicon nanoantennas to enhance light-matter interaction. The wealth of resonances of the individual dielectric nanoparticles allowed us to see collective resonances with both electric and magnetic dipole character. We demonstrated enhanced light emission and strong light-matter…
Online talk in SPIE Photonics Europe
Thanks to SPIE, now you can watch Raziman’s presentation “Chirality in evanescent fields: conditions, limits, and guidelines”
Photonics Society Eindhoven
Photonics Society Eindhoven (PhE) (https://phe.tue.nl) was born in 2019 as a PhD student organization to promote professional development, scientific outreach, and academic-industrial liaison around Photonics in Eindhoven. As faculty advisor, I want to take the opportunity to thank the PhDs of the Electrical Engineering and Applied Physics departments that are making these stimulating activities possible:…

Anisotropic infrared TiS3, in 2D Materials
Only a few van der Waals semiconductors emitting light at mid-infrared telecom wavelengths have been demonstrated so far. Examples are black phosphorus or molybdenum ditelluride, but they suffer from photostability issues. In our recent article “Anisotropic infrared light emission from quasi-one-dimensional layered TiS3”, by Ali Khatibi and colleagues, we demonstrate that titanium trisulfide is a…
Most read in ACS Photonics
Our recent article “Conditions for enhancing chiral nanophotonics near achiral nanoparticles” has made it to the top of the most read articles in ACS Photonics for the last month (November and December 2019). The article proposes conditions, guidelines, and limits to exploit evanescent fields near nanostructures for chiral applications. Circularly polarized light is the basis…
Chiral evanescent waves in ACS Photonics
Enhancing the intensity of chiral fields with nanophotonic structures? Yes, but conditions and limits apply for maximum chirality. See our article “Conditions for Enhancing Chiral Nanophotonics near Achiral Nanoparticles” in ACS Photonics.
Quality control for processed 2D semiconductors
Making optoelectronic and nanophotonic devices out of monolayer semiconductors requires processing of these fragile 2D materials. Usual processes involve creating heterostructures, transferring to a different substrate, or encapsulation in a dielectric superstrate. Together with our TU/e collaborators, we have used fluorescence lifetime imaging to check the quality of WS2 after different processing steps. We find…

Limits to strong coupling, in ACS Photonics
Our collaboration with the groups of Jaime Gómez Rivas (TU/e) and Bjorn Maes (University of Mons, BE) is now published in ACS Photonics. We demonstrate experimentally and theoretically that strong light-matter coupling between excitons in 2D semiconductors and arrays of metal nanoparticles reaches saturation due to dielectric screening as the thickness of the semiconductor increases.…

Magnetic mirrors in Nature Communications
Our article Optical emission near a high-impedance mirror, now published in Nature Communications. By nanostructuring a silver film, we show that it is possible to suppress surface plasmon excitation (a loss mechanism in organic LEDs) while having maximum emission. The results lead to metallic electrodes with lower losses.

Our lab specializes in nanophotonic structures made of bulk and atomically thin semiconductors. Our main techniques are: Confocal fluorescence microscopy and spectroscopy, covering the ultraviolet, visible and near infrared.
