“For nearly an hour and 15 minutes, Balog and his crew stood by and watched as a piece of ice the size of lower Manhattan — but with ice-equivalent buildings that were two to three times taller than that — simply melted away” upworthy.com/largest-proof-…

Remarkable! “waveguide-coupled high-Q silicon photonic cavities that confine telecom photons to 2 nm air gaps with an aspect ratio of 100, corresponding to mode volumes more than 100 times below the diffraction limit” nature.com/articles/s4158…

The authors “advocate for the value of learning and surprise, and for an irreverence for boundaries of all kind — between disciplines, science and technology” This was the Bell Labs culture and became the guiding light for my own research! nature.com/articles/s4225…

A big leap in space for our metalenses! Congratulations to Joon-Suh Park for leading the charge! pubs.acs.org/doi/abs/10.102… seas.harvard.edu/news/2024/01/m…

The Mid-infrared has lagged behind in Integrated Photonics: but here we demonstrate the integration of Mid-IR ring resonators and directional couplers, incorporating a quantum cascade active region in the waveguide core nature.com/articles/s4146…

Exciting AI advance! NY Times quotes lead author Dr. Trinh: “We’re not making incremental improvement,” he said. “We’re making a big jump, a big breakthrough in terms of the result.” “Just don’t overhype it,” he said. nature.com/articles/s4158…

Physics In History This is entirely true. Any neural system, any brain, is constantly seeking truth for survival and can find completely unique ways to discover new truths. No two people who can communicate with other people in natural language can escape the gift of their unique knowledge and

When drawing water, the sprinkler alters its direction of rotation, leading to a more erratic and slower movement. This behavior is due to the specifics of how fluid moves through the sprinkler's structure. Fluid mechanics is a most complex science! physics.aps.org/articles/v17/15

Solitons on demand! We demonstrate solitons that are stable in a ring laser and form spontaneously with tuning laser bias, eliminating the need for an external optical pump. Congrats to a great international team! nature.com/articles/s4158…

First image of solar eclipse with a metalens telescope! Taken by my student Arman Amirzhan at a site near Irasburg, Vermont (44°49'50.5"N 72°14'23.8"W) on 4/8/2024. The 10 cm glass metalens was fabricated by my postdoc Joon-Suh Park. Note the flare from the corona near hour 2.

Here’s the paper on our 10 cm metalens with which we imaged the total solar eclipse yesterday. The image quality of the nebula, sun and moon exceeds that achieved with more complex telescope optics. pubs.acs.org/doi/abs/10.102…
