Coupled micro-resonators for second-order integrated nonlinear optics
We investigate second-order nonlinear processes in a system of two coupled identical optical micro-resonators. The double resonance and phase-matching conditions are simultaneously obtained thanks to the frequency splitting induced by the resonator coupling. The analysis made in the framework of the coupled mode theory is applied to the second harmonic generation process in two whispering gallery mode microdisks made in III-V materials.

Amid Trump standoff, Smithsonian says only secretary can hire and fire
The Smithsonian’s Board of Regents said on Monday night that
“all personnel decisions” are directed by Secretary Lonnie G. Bunch III,
10 days after Donald Trump claimed that he had fired the director of the institution’s National Portrait Gallery.
The board, which issued its statement after an all-day meeting Monday, also said that it supported Bunch’s “authority and management” of the Smithsonian…

Amid Trump standoff, Smithsonian says only secretary can hire and fire
The Board of Regents publicly backed Smithsonian leader Lonnie G. Bunch III and called for nonpartisanship after Trump attempted to fire a museum director.

I missed today's protest because I had client work but clients paying me for work helps fuel the efforts in put into the community.
I got a bunch of supplies recently to make more unhoused person care packages and I purchased art from marginalized people that will be made available in the Free Little Art Gallery.
We all gotta do what we can, when we can, in the ways we can.

Monitoring Single DNA Docking Site Activity With Sequential Modes of an Optoplasmonic Whispering-Gallery Mode Biosensor
In recent years, there has been rapid advancement in single-molecule techniques, driven by their unparalleled precision in studying molecules whose sizes are beyond the diffraction limit. Among these techniques, optoplasmonic whispering gallery mode sensing has demonstrated great potential in label-free single-molecule characterization. It combines the principles of localized surface plasmon resonance (LSPR) and whispering gallery mode (WGM) sensing, offering exceptional sensing capabilities, e…

‘Suspended animation’: US government upheaval has frayed partnerships with critical infrastructure
Recent federal cuts, reorganizations and other disruptions have alarmed industry leaders, who say the government is a less reliable partner even as cyber threats increase.

Bistable random momentum transfer in a linear on-chip resonator
Optical switches and bifurcation rely on the nonlinear response of materials. Here, we demonstrate linear temporal bifurcation responses in a passive multimode microresonator, with strongly coupled chaotic and whispering gallery modes or WGMs. In microdisks, the chaotic modes exhibit broadband transfer within the deformed cavities, but their transient response is less explored and yields a random output of the analog signal distributed uniformly from 0 to 1. Here, we build chaotic states by per…

Recent advances in DNA origami-engineered nanomaterials and applications
DNA nanotechnology is a unique field, where physics, chemistry, biology, mathematics, engineering, and materials science can elegantly converge. Since the original proposal of Nadrian Seeman, significant advances have been achieved in the past four decades. During this glory time, the DNA origami technique developed by Paul Rothemund further pushed the field forward with a vigorous momentum, fostering a plethora of concepts, models, methodologies, and applications that were not thought of befor…

Nonlinear Symmetry Breaking to Enhance the Sagnac Effect in a Microresonator Gyroscope
Optical gyroscopes based on the Sagnac effect have been widely used for inertial navigation in aircrafts, submarines, satellites and unmanned robotics. With the rapid progress in the field of ultrahigh-quality whispering gallery mode and ring resonators in recent years, these devices offer the promise of a compact alternative to ring-laser gyroscopes (RLGs) and fiber-optic gyroscopes (FOGs). Yet, successful commercialization of a microresonator gyroscope has been hindered by the scaling of the …
