Refraction of space-time wave packets in a dispersive medium
Murat Yessenov, Sanaz Faryadras, Sepehr Benis +3
Space-time (ST) wave packets are a class of pulsed optical beams whose spatio-temporal spectral structure results in propagation invariance, tunable group velocity, and fascinating…
Severing the link between modal order and group index using hybrid guided space-time modes
Abbas Shiri, Ayman F. Abouraddy
The structure of an optical waveguide determines the characteristics of its guided modes, such as their spatial profile and group index. General features are shared by modes regard…
Space-time wave packets localized in all dimensions
Murat Yessenov, Justin Free, Zhaozhong Chen +4
Optical wave packets that are localized in space and time, but nevertheless overcome diffraction and travel rigidly in free space, are a long sought-after field structure with appl…
A universal angular-dispersion synthesizer
Layton A. Hall, Ayman F. Abouraddy
We uncover a surprising gap in optics with regards to angular dispersion (AD) that has persisted for decades. A systematic examination of pulsed optical-field configurations classi…
The consequences of non-differentiable angular dispersion in optics: Tilted pulse fronts versus space-time wave packets
Layton A. Hall, Ayman F. Abouraddy
Conventional diffractive and dispersive devices introduce angular dispersion (AD) into pulsed optical fields thus producing so-called 'tilted pulse fronts'. Naturally, it is always…
Arbitrarily accelerating space-time wave packets
Layton A. Hall, Murat Yessenov, Ayman F. Abouraddy
All known realizations of optical wave packets that accelerate along their propagation axis, such as Airy wave packets in dispersive media or wave-front-modulated X-waves, exhibit…
