Entropic thermodynamics of nonlinear photonic chain networks
Fan O. Wu, Pawel S. Jung, Midya Parto +2
The complex nonlinear behaviors of heavily multimode lightwave structures have been recently the focus of considerable attention. Here we develop an optical thermodynamic approach…
Multi-wavelength high energy gas-filled fiber Raman laser spanning from 1.53 um to 2.4 um
Abubakar I. Adamu, Yazhou Wang, MD. Selim Habib +5
In this work, we present a high pulse energy multi-wavelength Raman laser spanning from 1.53 um up to 2.4 um by employing the cascaded rotational stimulated Raman scattering (SRS)…
Noise performance and long-term stability of near- and mid-IR gas-filled fiber Raman lasers
Yazhou Wang, Abubakar Isa Adamu, Manoj Kumar Dasa +5
In this letter, the characteristics of noise and long-term stability of near- and mid-infrared (near-IR and mid-IR) gas-filled fiber Raman lasers have been investigated for the fir…
Coherent perfect absorption in resonant materials
S. Shabahang, Ali. K. Jahromi, L. N. Pye +3
Coherent perfect absorption (CPA) is an interferometric effect that guarantees full absorption in a lossy layer independently of its intrinsic losses. To date, it has been observed…
Spectrally recycling space-time wave packets
Layton A. Hall, Ayman F. Abouraddy
'Space-time' (ST) wave packets are propagation-invariant pulsed optical beams that travel rigidly in linear media without diffraction or dispersion at a potentially arbitrary group…
Axial spectral encoding of space-time wave packets
Alyssa Allende Motz, Murat Yessenov, Ayman F. Abouraddy
Space-time (ST) wave packets are propagation-invariant pulsed optical beams whose group velocity can be tuned in free space by tailoring their spatio-temporal spectral structure. T…
