In this letter, we propose to realize optical discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) on one single multimode interference (MMI) coupler. In comparison to the ...

Nanoparticles (NPs) are materials whose dimensions range from 1 to 1,000 nanometers (nm). Due to their nano-scale dimensions ...

Abstract: We investigated the correlation between the temperature coefficient of elasticity (TCE) and Fourier transform infrared (FT-IR) absorption spectra of SiO 2 for SAW devices. The measurement ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition ...

Mamyshev oscillators (MOs) can emit high energy pulses using a laser generation technique known as harmonic mode-locking (HML). While MO employing HML has several advanced applications in varied ...

Nanoparticles (NPs), materials with sizes ranging from 10 to 1,000 nm, are increasingly utilized as drug-delivery systems and ...

A Fourier transform of the recorded voltage and current data thus yields an impedance spectrum. (33,35) Using this approach, we can collect a complete impedance spectrum on the time scale defined by ...

Findings show water vapor absorption leads to wrinkling in plasma-oxidized PDMS, crucial for advancing reversible optical ...

Researchers investigate the interaction dynamics of bovine serum albumin and silica nanoparticles using spectroscopy methods.

"The starting dynamics of HML in the MO, characterized by the time-stretch dispersive Fourier transform technique (TS-DFT ... Well, unlike many news organisations, we have no sponsors, no corporate or ...

A study found glass bottles leak more microplastics into drinks than plastic bottles or cans. The main source? Paint from the ...
