Electrically injected parity-time symmetric distributed feedback laser diodes (DFB) for telecom applications

Vincent Brac de la Perrière, Quentin Gaimard, Henri Benisty, Abderrahim Ramdane, Anatole Lupu
2021 Nanophotonics  
AbstractThe new paradigm of parity-time symmetry in quantum mechanics has readily been applied in the field of optics with numerous demonstrations of exotic properties in photonic systems.  ...  Optical transmission probing experiments further show asymmetric amplification in the light propagation confirming the parity-time symmetry signature of unidirectional light behavior.  ...  Author contributions: All the authors have accepted responsibility for the entire content of this submitted manuscript and approved submission.  ...

On-chip quantum and nonlinear optics: from squeezing to spectroscopy

Avik Dutt
2017
We conclude our exploration of quantum photonics in silicon nitride with a path towards deterministic entanglement generation.  ...  Quantum and nonlinear optics has garnered a lot of interest in the last few decades due to its applications in a plethora of fields such as sensing, spectroscopy, frequency metrology and quantum information  ...  In the language of quantum electrodynamics, the four-photon vertex for the Feynman diagram of photon-photon scattering is very weak in vacuum.  ...

Optical Properties of TMDC Monolayers and Their Heterostructures

Lorenz Maximilian Schneider, Koch, Martin (Prof. Dr.), Physik
2020
To do that effectively and systematically, several questions need to be addressed, to the answering of which the following studies contribute with important insights focusing on the optical properties  ...  Furthermore, van-der-Waals stacking of different 2D crystals results in out-of-plane heterostructures, which can, in addition to the inherited properties of the individual layered constituents, even exhibit  ...  In contrast, if very small signals with small SNR are present, the intensity is analyzed by means of statistical photon counting.  ...

Experiments in Nonlinear Optics with Epsilon-Near-Zero Materials [article]

Mohammad Zahirul Alam, University, My
2020
However, the changes to the refractive index of a material due to the presence of a strong laser beam are very weak---maximum on the order of $10^{-3}$---and tend to be a small fraction of the linear refractive  ...  Thus, one of the foundational assumptions of nonlinear optics is that the nonlinear optical changes to material properties are always a small perturbation to the linear response.  ...  R ACKNOWLEDGMENTS We gratefully acknowledge the support of the Canada Excellence Research Chair (CERC) program and from NSERC.

Hole Spin Qubits in Ge/Si Core/Shell Nanowires

Florian N. M. Froning
2021
Quantum dots in the common semiconductors Si and Ge profit from the compatibility with industrial microelectronic technologies, a small footprint, and thermal stability.  ...  Spins in semiconductor quantum dots are among the most promising candidates for the realization of a scalable quantum bit (qubit), the basic building block of a quantum computer.  ...  Thank you for all the support, and everything I could learn about physics, lab work, and many other things. I enjoyed all the fantastic dinners, BBQs and excursions.  ...

Scattering engineering at the extreme with metamaterials, metasurfaces and nanostructures [article]

Francesco Monticone
2016
No act of kindness, no matter how small, is ever wasted.  ...  Andrea Alù, for believing in me and for guiding me throughout these years. The best decision of my professional life has been to enroll in UT Austin, and join the group of Dr. Alù.  ...  When we have some control of the arrangement of things on a small scale we will get an enormously greater range of possible properties that substances can have, and of different things that we can do.  ...
