Creating traveling waves from standing waves from the gyrotropic paramagnetic properties of Fe ions in a high-Q whispering gallery mode sapphire resonator

چکیده
We report observations of the gyrotropic change in magnetic susceptibility of the Fe electron paramagnetic resonance at 12.037GHz (between spin states |1/2 > and |3/2 >) in sapphire with respect to applied magnetic field. Measurements were made by observing the response of the high-Q Whispering Gallery doublet (WGH±17,0,0) in a Hemex sapphire resonator cooled to 5 K. The doublets initially existed as standing waves at zero field and were transformed to traveling waves due to the gyrotropic response.

Frequency conversion in a high Q-factor sapphire whispering gallery mode resonator due to paramagnetic nonlinearity.
Nonlinear frequency conversion is a well known and widely exploited family of effects in optics, often arising from a Kerr nonlinearity in a crystal medium. Here, we report high stability frequency conversion in the microwave regime due to a χ(3) nonlinearity in sapphire introduced by a dilute concentration of paramagnetic spins. First, we produce a high stability comb from two microwave fields...
متن کاملFour-wave mixing from Fe3+ spins in sapphire.
Fe(3+) ions in sapphire exhibit an electron spin resonance which interacts strongly with high-Q whispering gallery modes at microwave frequencies. We report the first observation of a third-order paramagnetic nonlinear susceptibility in such a resonator at cryogenic temperatures and the first demonstration of four-wave mixing using this parametric nonlinearity. This observation of an all-microw...
متن کاملOptical rogue waves in whispering-gallery-mode resonators
We report a theoretical study showing that rogue waves can emerge in whispering-gallery-mode resonators as the result of the chaotic interplay between Kerr nonlinearity and anomalous group-velocity dispersion. The nonlinear dynamics of the propagation of light in a whispering-gallery-mode resonator is investigated using the Lugiato-Lefever equation, and we give evidence of a range of parameters...

متن کاملWhispering gallery modes
Whispering gallery modes are specific resonances (or modes) of a wave field that are confined inside a given resonator (cavity) with smooth edges due to continuous total internal reflection. The most interesting from a practical viewpoint are electromagnetic whispering gallery modes, since they posses many unique properties, such as ultra-high Q-factors, low mode volumes, small sizes of resonat...
