Figure 1: Broadband parametric frequency conversion from a monolithic toroidal microresonator. Note that the residual cavity dispersion exceeding the ‘cold’ cavity linewidth does not preclude the ...

At the beginning of the year, I attended a conference called “Physics of Quantum Electronics,” where I learned about something called coherent perfect absorbers (CPA). At the time, I didn’t write ...

Silicon nanophotonic waveguides are the ideal platform for creating mid-infrared devices such as optical parametric amplifiers, say IBM researchers. A new generation of efficient and ultra-compact ...
