Designing the femtosecond optical oscilloscope

Abstract

We present the results of our recent experimental and numerical studies on femtosecond pulse spectrotemporal imaging in a similariton-induced temporal lens aimed to designing a femtosecond optical oscilloscope [1]. We have studied nonlinear and dispersive peculiarities of modern high-tech materials, such as photonic crystal fibers, hollow-core fibers etc, to use them in the scheme, and to provide compactness and reliability of the device. The use of hollow-core fibers, as a dispersive medium instead of a pair of prisms or gratings, is of special importance for constructing the industrial tool. Additionally, we are experimenting on the method of dispersive Fourier transformation, using the effect of chromo-modal dispersion in multimode fibers [2], to provide real-time performance of the device.

High Wideband Digital Oscilloscope Design

“…With advances in microelectronics and digital signal processing (DSP) technology, digital oscilloscopes are able to process complex signals more efficiently and provide higher performance [1][2]. The increasing complexity of modern electronic devices and systems requires higher-level test and measurement tools to ensure their performance and reliability.…”
