Amplification and attenuation of light in a waveguide modulated by a travelling wave
M. Sumetsky
Light propagating in an optical waveguide can gain or lose power through interaction with a travelling acoustic wave or radio-frequency modulation of permittivity. Here, we model t…

Complete inelastic transparency of time-modulated resonant photonic circuits
M. Sumetsky
Photonic circuits modulated in time can convert the input light frequency shifting it by multiples of the modulation frequency and, in certain cases, amplify the tota…

Transformation and amplification of light modulated by a traveling wave with a relatively low frequency
M. Sumetsky
The behavior of electromagnetic waves in media modulated in both time and space, extensively studied decades ago, has recently attracted renewed attention. In this work, we address…
