Thanks to an ERC Starting Grant from the European Research Council, we will perform the project CHANSON on chiral semiconductor nanophotonics. We will push the limits of sensitivity and resolution in chiral molecular detection using semiconductor nanostructures. Deeply grateful to my team for helping me in laying its foundations. We have PhD and postdoc openings, […]

Just published in Nano Letters: Correlated exciton fluctuations in a two-dimensional semiconductor on a metal. Congratulations Rasmus!
Alberto has received tenure, becoming permanent academic staff after less than 4 years in the tenure track at TU/e. Thank you to the team for making it happpen!
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, […]
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 […]
Thanks to SPIE, now you can watch Raziman’s presentation “Chirality in evanescent fields: conditions, limits, and guidelines”
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: […]
Ershad Mohammadi has recently started as a postdoctoral researcher in the Nano-Optics lab at TU/e. His work focuses on chiral and spin nanophotonics.
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 […]
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 […]
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.
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 […]
Sara Elrafey has recently started her PhD in the Nano-Optics@TU/e team. Her thesis focuses on 2D semiconductors for Nanophotonics.
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. […]
The Netherlands Organisation for Scientific Research (NWO) has awarded a START-UP grant to TU/e Assistant Professor Alberto G. Curto at the Department of Applied Physics and the Institute for Photonic Integration. The NWO START-UP grant “gives new principal investigators the opportunity to refine their creative, high-risk ideas, to establish a basis for future research themes, […]

We are based in Eindhoven, a city with a sustained tradition of industrial and scientific developments in the science and technology of light. Our team is part of the extended Photonics and Semiconductor Nanophysics group at TU/e http://www.tue.nl/psn We are also part of the Institute for Photonic Integration https://www.tue.nl/en/research/research-centers/institute-for-photonic-integration/
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 and two-dimensional semiconductors. Our main techniques are: Confocal photoluminescence microscopy and spectroscopy, covering the visible, near infrared, and mid-infrared. Low-temperature optical measurements with optical microscopy cryostats. Luminescence lifetime and photon correlation measurements. Polarization-resolved luminescence, with linear or circular polarization. Modelling of the optical response of nanophotonic structures with 3D […]
Good news for Photonics @ TU/e: the recently approved “National Plan for Integrated Photonics” will strengthen our ecosystem. Together with local companies and the university, several government bodies (national, regional, and local) are investing heavily in a clear bet for the Photonics industry. Very glad to see “Fotonica” on the cover of a local newspaper, […]
