Comment on "Nonreciprocal cavities and the time-bandwidth limit"

Kosmas L. Tsakmakidis, Yun You, Tomasz Stefanski +1

In their paper in Optica 6, 104 (2019), Mann et al. claim that linear, time-invariant nonreciprocal structures cannot overcome the time-bandwidth limit, and do not exhibit an advan…

A nonreciprocal optical resonator with broken time-invariance for arbitrarily high time-bandwidth performance

Ivan Cardea, Davide Grassani, Simon J. Fabbri +6

Most present-day resonant systems, throughout physics and engineering, are characterized by a strict time-reversal symmetry between the rates of energy coupled in and out of the sy…
