Doppler Effect as a tool for ultrashort electric field reconstruction.
Optics letters, 2020Co-Authors: P Béjot, E Szmygel, A Dubrouil, F Billard, B Lavorel, O Faucher, E HertzAbstract:We present a new, to the best of our knowledge, variant of the spectral-shearing interferometry method for characterizing ultrashort laser pulses. This original approach, called Doppler Effect e-field replication (DEER), exploits the rotational Doppler Effect for producing frequency shear and provides spectral shearing in the absence of frequency conversion, enabling operation in the ultraviolet spectral range. Evaluation of the DEER-spectral phase interferometry for direct electric field reconstruction setup reveals a phase reconstruction of great reliability. Possible improvements, benefits, and worthwhile prospects of the method are discussed.

Doppler Effect as a tool for ultrashort electric field reconstruction
arXiv: Optics, 2020Co-Authors: P Béjot, E Szmygel, A Dubrouil, F Billard, B Lavorel, O Faucher, E HertzAbstract:Technological advances in femtosecond laser sources call for the development of increasingly refined characterization tools implying to enrich the existing panel of operable nonlinear interactions. The present paper describes a novel characterization method based on spectral-shearing interferometry which exploits the non-standard rotational Doppler Effect for producing the frequency shear. This original approach, called DEER "Doppler Effect for Electric field Reconstruction", provides a spectral-shearing in the absence of frequency conversion and features multiple benefits as for instance the ability of operation in the ultraviolet spectral range or the characterization of ultra-broadband laser pulses.

superlight inverse Doppler Effect
Nature Physics, 2018Co-Authors: Xihang Shi, Ido Kamine, Zhaoju Yang, Mari Soljacic, John D. Joannopoulos, Fei Gao, Aile ZhangAbstract:It has long been thought1 that the inverse Doppler frequency shift of light2–13 is impossible in homogeneous systems with a positive refractive index. Here we break this long-held tenet by predicting a previously unconsidered Doppler Effect of light inside a radiation cone, the so-called Vavilov–Cherenkov cone, under specific circumstances. It has been known from the classic work of Ginzburg and Frank that a superlight (that is, superluminal) normal Doppler Effect14–18 appears inside the Vavilov–Cherenkov cone if the velocity of the source v is larger than the phase velocity of light vp. By further developing their theory, we discover that an inverse Doppler frequency shift will arise if v > 2vp. We denote this as the superlight inverse Doppler Effect. Moreover, we show that the superlight inverse Doppler Effect can be spatially separated from the other Doppler Effects by using highly squeezed polaritons (such as graphene plasmons), which may facilitate the experimental observation. The authors theoretically investigate a novel form of a Doppler Effect in homogeneous systems with positive refractive index that occurs under certain conditions. It is suggested that this Doppler Effect can be experimentally separated from other Doppler Effects by using polaritons such as those found in graphene.

superlight inverse Doppler Effect
arXiv: Optics, 2018Co-Authors: Xihang Shi, Ido Kamine, Zhaoju Yang, Mari Soljacic, John D. Joannopoulos, Fei Gao, Aile ZhangAbstract:There is a century-old tenet [1, 2] that the inverse Doppler frequency shift of light [3-13] is impossible in homogeneous systems with a positive refractive index. Here we break this long-held tenet by predicting a new kind of Doppler Effect of light inside the Cherenkov cone. Ever since the classic work of Ginzburg and Frank, it has been known that a superlight (i.e., superluminal) normal Doppler Effect [14-18] appears inside the Cherenkov cone when the velocity of the source v is larger than the phase velocity of light v_p. By further developing their theory we discover that an inverse Doppler frequency shift will arise when v>2v_p. We denote this as the superlight inverse Doppler Effect. Moreover, we show that the superlight inverse Doppler Effect can be spatially separated from the other Doppler Effects by using highly squeezed polaritons (such as graphene plasmons), which may facilitate the experimental observation.

the superlight inverse Doppler Effect
Conference on Lasers and Electro-Optics, 2018Co-Authors: Xihang Shi, Ido Kamine, Zhaoju Yang, Mari Soljacic, John D. Joannopoulos, Fei Gao, Aile ZhangAbstract:An inverse Doppler frequency shift of light, i.e., superlight inverse Doppler Effect, is shown possible even in homogeneous media with positive-refractive index, contrary to the status quo ante. We show an example with graphene plasmons.
