IRT 1 — ENZ XPM platform for QND detection IRT 1 develops low-loss, strongly nonlinear ENZ (meta)materials that maximize MWIR cross-phase modulation (XPM) for quantum nondemolition (QND) measurements, while managing loss and damage thresholds. The thrust...

The QEMISD MURI program aims to enable room-temperature quantum nondemolition (QND) detection of single midwave infrared (MWIR) photons—distinguishing them from thermal background photons—by exploiting extreme nonlinear optical responses in epsilon-near...

Long-range quantum entanglement in dielectric mu-near-zero metamaterials

Journal Article

Entanglement is paramount in quantum information processing. Many quantum systems suffer from spatial decoherence in distances over a wavelength and cannot be sustained over short time periods due to dissipation. However, long range solutions are required...

Dynamic control of intrinsic optical chirality via MEMS-integrated photonic crystals

Journal Article

Chiral nanophotonic structures offer unprecedented design flexibility for enhancing chiral optical responses, yet dynamic tuning of such responses remains a key challenge. Here, we demonstrate intrinsic optical chirality tunability in reconfigurable...

Probing quantum geometry through optical conductivity and magnetic circular dichroism

Journal Article

Probing ground-state quantum geometry and topology through optical responses is not only of fundamental interest, but it can also offer several practical advantages. Here, using first-principles calculations on thin films of the antiferromagnetic...

Flat-Band Photonic Waveguides

Conference Paper

We experimentally demonstrate a moiré photonic crystal waveguide, achieving adjustable flat band count and flatness by varying moiré periodicity and modulation strength. We confirm the observation of flat bands with a minimum 6-nm bandwidth.
