I am an Assistant Professor of photonics and optical physics in the Wyant College of Optical Sciences, University of Arizona.

@igordownunder @MitQpg Yeah, i think we removed it now :D i truly believe in it though. A single tape out in Si Photonics costs > $100K. A CMOS tape out costs only a few thousand dollars (6K now) and gives you 100 chips within 3 months-so making 3D meta-materials is now cheaper than PICs!

[Mohamed ElKabbash @MElkabbash]

Our latest work. We used the wires in a CMOS chip to create metal-optic devices, thus enabling monolithic integration of photonics and electronics in the most widely used semiconductor foundry processes.

Did we just start a revolution in nano-photonics? By repurposing metal layers in a standard CMOS fabrication process, @MElkabbash, Sivan Trajtenberg-Mills and collaborators create a 40 KHz liquid crystal optical modulator in a "fabless" model. https://t.co/ZPpair6O87

@MitQpg We created a 40 KHz liquid crystal optical modulator in a semiconductor foundry process that is originally intended for electronic integrated circuits.

[Mohamed ElKabbash @MElkabbash]

@MitQpg What we realized is that the wires used as interconnects in a CMOS chip can be repurposed into a metal-optic device, allowing the monolithic integration of nanophotonics and electronics in the same process.

[Mohamed ElKabbash @MElkabbash]

@MitQpg Monolithic integration of photonics and electronics so far had a single venue; Silicon Photonics. The vast majority of the semiconductor industry, however, is done in bulk Silicon CMOS foundries which do not support photonic devices.

Just out our latest results on Fano resonant optical coatings (FROCs) for high purity structural colors. Awesome work @MElkabbash @denehoffman and Andy Lininger. @NanoplasmC @PhysicsCWRU @nanoplasmlab @hinczewskilab @OpticaWorldwide

Our work on extending the lifetime of excitons in perovskites for better perovskite-based optoelectronic devices is just out in @NaturePhotonics !!
congrats to Kwangjin and the team @guolaserlab .

[Mohamed ElKabbash @MElkabbash]

We showed that the interplay of trapping and detrapping dynamics along with the screening of the in-plane exciton decay can explain this "gigantic" increase in lifetime.

[Mohamed ElKabbash @MElkabbash]

.. (3) somewhat surprisingly, the exciton lifetime increase even on hyperbolic metamaterials, and (4) the lifetime increase by a factor of TEN for trication perovskites!! to put this in context, this increase is only realized in photonic crystals

[Mohamed ElKabbash @MElkabbash]

The work describes the unusual dynamics of excitons in lead halide perovskite thin films. We discovered that (1) the excitons are anisotropic with in-plane orientation, (2) the lifetime extends when placed on a metal film, ..

We have a job posting for a process engineer in nanofabrication : https://t.co/Q7JSPEMNjY

[Mohamed ElKabbash @MElkabbash]

Out on arxiv, our work on on-chip metasurfaces for wavelength division demultiplexing.
@guolaserlab
Special thanks to @alqulaiaaamjed who led the work

[Mohamed ElKabbash @MElkabbash]

A new type of optical coatings that provides an ideal platform for structural coloring. In collaboration with @hinczewskilab @PStrangi @guolaserlab
Special thanks to to Dene @denehoffman and Andy Lininger who lead the work.

[Mohamed ElKabbash @MElkabbash]

Can we realize efficient daytime radiative cooling even in humid environments, check our new work on arxiv to know the answer

[Mohamed ElKabbash @MElkabbash]

Hot off the press. Our work on the impact of imposing angularly selective thermal emission on radiative cooling. We propose a simple method to create angularly selective thermal emitters.
