Researchers have used Raman and PL spectroscopy to explore the opto-thermal transport in lithographically patterned MAPbI3 thin films, establishing an operable thermal window for #perovskite metasurfaces with optimal optical efficiencies. Saswata Halder fal.cn/3h7Pe

A paradigm shift in chip scale hybrid photonic-atomic devices. Our new work on the nanoscale membrane like waveguide with alkali vapor cladding has been published in #naturephotonics. Read all about it here: rdcu.be/crnai #nanophotonics #waveguides #Rubidium #frequency

Researchers at Hebrew University have demonstrated how the one atom thick material graphene can be implemented as a neuromorphic transistor. The device emulates the behaviour of a biological neuron and can be stimulated with UV light or electrically. fal.cn/3iesm /#PHAR

And now this work is highlighted on the cover of Nature Photonics #naturephotonics. Thank you team for the great job. Congratulations Roy!!

Metalenses and spectral gating are combined together to provide high accuracy 3-D imaging. Neither scanning no time gating is needed. The approach provides real time parallel imaging in 3d. See our recent paper in ACS NANO. pubs.acs.org/doi/10.1021/ac…

#Metalenses and #diffractive #lenses are everywhere, from consumer electronics to aerospace. But are they good or not? Literature is confusing, and is lacking standardization. Our Nature Photonics paper defines approaches for flat lens characterization. rdcu.be/cHuNw

Chip scale spectroscopy, artificial intelligence, and machine learning algorithms are integrated with alkali Rubidium vapor to establish an accurate miniaturized wavemeter. See our science advances paper #waveguides #AI #photonics #spectrometer science.org/doi/10.1126/sc…

Our recent #scienceadvances paper demonstrates a color display implemented by structural plasmonic colors. Tunability is achieved by adding a MEMS cantilever. This is a fully recyclable CMOS compatible device. See also the journal cover. #MEMS #Plasmonics science.org/doi/10.1126/sc…

In the article below I discuss opportunities and challenges of metalenses, dwelling on generating a unified standard to evaluate the performance of metalenses. . #metalens #metasurfaces #flat optics #miniaturization #photonics MAFO - 01/2023 issuu.com/eyepressfachme… via Issuu

Silicon nitride is a promising platform for integrated nanophotonics. Unfortunately, it cannot be used for photodetection. Based on a MoSe2/WS2 heterostructure , we integrated a photodetector into this platform. See our paper rdcu.be/c7aLC Bravo Rivka Gherabli et al.

We are on the cover of Science Advances! with the optical version of the ESAKI negative resistance diode, providing optical readout using silicon photonics. #siliconphotonics #nano #photonics science.org/doi/10.1126/sc…

To overcome the major challenge of proper material selection for visible meta optics, we demonstrate silicon rich nitride (SRN) for visible light meta optics in the visible range. See our paper below. #metasurface #nanophotonics #flatoptics metasurface onlinelibrary.wiley.com/doi/10.1002/ad…

Going back to science is the best way to overcome the October 7 brutal and vicious terror attack by Hamas terrorists on the south-west of Israel. Read our new paper: Achromatic Imaging Systems with Flat Lenses Enabled by Deep Learning | ACS Photonics pubs.acs.org/doi/full/10.10…

high Q nanophotonic resonators are highly desired in chip scale integrated optics. Not of a lesser importance is achieving high finesse. Here we demonstrate both. #nanotechnology #siliconphotonics #resonance #optics #optoelectronicsReading #OSA_OpEx opg.optica.org/oe/fulltext.cf…

TMDCs are excellent candidates as broadband photodetectors and image sensors. We have enhanced their capabilities by the integration with hyperbolic metamaterial cavities. #nanophotonics #photodetectors #SWIR #metamaterials #metasurfaces #image #sensors pubs.acs.org/doi/full/10.10…
