Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics, has been awarded a 2023 Sloan Research Fellowships. Awarded annually since 1955 by the Alfred P. Sloan Foundation, the fellowships "honor extraordinary U.S. and Canadian researchers whose creativity, innovation, and research accomplishments make them stand out as the next generation of leaders," according to the foundation's announcement. A total of 156 Caltech researchers have received the awards to date. [Caltech story]

Electronic computing and communications have come a very long way since the days of radio telegraphy and vacuum tubes, with consumer devices now containing levels of processing power and memory that would be unimaginable just a few decades ago. "The quality of the quantum states we have achieved surpasses the requirements for quantum information processing, which used to be the territory of bulky experimental setups," says Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics.

The Caltech Center for Sensing to Intelligence (S2I) has announced that, in collaboration with Rockley Photonics, a photonics-based health monitoring and communications solutions company, it will allocate $1.5 million in research grants over the next three years to jumpstart efforts to combine sensors with artificial intelligence. "We would like to have sensors in every device these days, generating a huge amount of data," says Azita Emami, Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering and the director of S2I. "But it's difficult to extract the most important information from the mountains of data they create." [Caltech story]

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]
