Tutorial on Fourier Transform for Ultrafast Optics

Published: Jan. 23, 2025

This tutorial is designed for individuals who are new to the field of ultrafast optics. It was written in response apparent lack comprehensive introductions basic Fourier transform, extending beyond flat-phase description. Additionally, there a need complete derivations several relations involving maintaining its most general formulation. approach avoids arbitrary selection Fourier-transform constants and ensures understanding. shows importance having as parameters, which I would like advocate people do. Most important all, have seen misuse transform over my years discussion lab from others’ questions since shared code publicly on Github [https://github.com/AaHaHaa/MMTools]. Surprisingly, check correctness numerical implementation only by seeing if simulation result smooth it duplicates “overall physics,” this seems be widespread problem perspective, can solved simple (see Sec. 2B). why hope that help understand more about especially context Feel me send an email any confusion, or you think add tutorial.

Tutorial on Fourier and Hankel Transforms for Ultrafast Optics

This tutorial is designed for individuals who are new to the field of ultrafast optics. It was written in response apparent lack comprehensive introductions basic Fourier transform, extending beyond flat-phase description. Additionally, there a need complete derivations several relations involving maintaining its most general formulation. approach avoids arbitrary selection Fourier-transform constants and ensures understanding. shows importance having as parameters. Most important all, have been misuse transform from my observations, which cannot be easily detected by checking smoothness result numerical implementation or seeing if simulation duplicates “overall physics.” problem should solved simple (see Sec. 2.2). I hope that this can help people understand more about especially context In addition, Hankel arises two-dimensional spatial radially-symmetric function, provided. Its based on fast with high accuracy also provided, core element full-field propagation. Feel me send an email any confusion, you think add tutorial. For deeper understanding into pulse propagation involves these transforms, please check out our publicly-shared Github code [https://github.com/AaHaHaa/MMTools].

Multi-megawatt pulses from 1030 nm to 1300 nm based on soliton self-frequency shifting in nitrogen-filled fiber

Optics Letters, Journal Year: 2025, Volume and Issue: 50(5), P. 1593 - 1593

Published: Jan. 29, 2025

Soliton formation and soliton self-frequency shift are investigated in a hollow-core fiber filled with N 2 gas. With 10-µJ 80-fs input pulses at 1030 nm, solitons greater than 500-nJ energy duration less 100 fs can be generated between 1090 1310 nm. peak powers above 5 MW, we expect that these will useful for applications such as nonlinear microscopy.

Entanglement transfer during quantum frequency conversion in gas-filled hollow-core fibers

APL Photonics, Journal Year: 2025, Volume and Issue: 10(4)

Published: April 1, 2025

Quantum transduction is essential for the future hybrid quantum networks, connecting devices across different spectral ranges. In this regard, molecular modulation in hollow-core fibers has proven to be exceptional efficient and tunable frequency conversion of arbitrary light fields down single-photon limit. However, insights into method have remained elusive beyond standard semi-classical models. Letter, we employ a Hamiltonian framework characterize behavior entanglement during while describing dynamics both molecules photons agreement with recent experiments. particular, apart from obtaining analytical expressions final opto-molecular states, our model predicts close correlation between evolution average photon numbers transfer interacting parties. These results will contribute development new fiber-based strategies tackle challenges associated upcoming generation lightwave technologies.
