Professor Phillips Awarded Feynman Teaching Prize
03-01-21
The 2021 Richard P. Feynman Prize for Excellence in Teaching, Caltech's highest teaching prize, has been awarded to Rob Phillips, Fred and Nancy Morris Professor of Biophysics, Biology, and Physics. The Richard P. Feynman Prize for Excellence in Teaching was established in 1993 to honor annually a professor who demonstrates, in the broadest sense, unusual ability, creativity, and innovation in undergraduate and graduate classroom or laboratory teaching. "Being a professor at Caltech has been the signature privilege of my professional life," says Phillips. "Though I am deeply honored by this award, I am also totally cognizant of the generations of students that have joined me in my teaching and research adventures and without whom, none of this would have been possible. I have been surrounded by so many brilliant and dedicated young scientists that have joined me in celebrating the sense of wonder that fuels our science." [Past recipients] [Caltech story]

New Insight into Nonlinear Optical Resonators Unlocks Door to Numerous Potential Applications
02-25-21
Devices known as optical parametric oscillators are among the widely used nonlinear resonators in optics; they are "nonlinear" in that there is light flowing into the system and light leaking out, but not at the same wavelengths. Though these oscillators are useful in a variety of applications, including in quantum optics experiments, the physics that underpins how their output wavelength, or spectrum, behaves is not well understood. "When you add strong nonlinearity to resonators, you enter what we call a 'rich physics regime,'" says Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics. "'Rich' in physics terms usually means complicated and hard to use, but we need nonlinearities to create useful functionalities such as switching for computing." To be able to make full use of nonlinear optical resonators, researchers want to be able to understand and model the physics that underpin how they work. Marandi and his colleagues recently uncovered a potential way to engineer those rich physics, while discovering phase transitions in the light that is generated by the resonators. [Caltech story]

Paul Rothemund Places Molecule-Scale Devices in Precise Orientation
02-22-21
Paul Rothemund, Research Professor of Bioengineering, Computing and Mathematical Sciences, and Computation and Neural Systems, has developed a technique that allows him to precisely place microscopic devices formed from folded DNA molecules in not only a specific location but also in a specific orientation. This method for precisely placing and orienting DNA-based molecular devices may make it possible to use these molecular devices to power new kinds of chips that integrate molecular biosensors with optics and electronics for applications such as DNA sequencing or measuring the concentrations of thousands of proteins at once.

Student-Led Moon Dust Shield Team Named Finalist in NASA Competition
02-16-21
As astronauts walk across the moon, land spacecraft on its surface, drive lunar rovers around, or complete other astronaut tasks, they kick up the dust, and that is a problem because it can cause premature wear on mechanical parts, damage to seals, and may pose a health risk for the people breathing it in. "The sun is shining directly on these particles and giving them an electric charge," says third-year Caltech undergraduate student Luis Pabon. "This causes it to stick to the astronaut's suit or to any sensors or cameras that you put out on the moon." The Caltech team's invention, named Habitat Orientable & Modular Electrodynamic Shield (HOMES), tackles the problem of moon dust entering a potential lunar habitat and wreaking havoc within.
