Experimentally, we demonstrate, to the best of our knowledge, the first observation of periodic spectrum changing via soliton explosion in a passively mode-locked fiber laser by a nonlinear polarization evolution. Using time stretch to capture 7220 c

Real-time Measurements, Rogue Phenomena, and Single-Shot Applications III.
The time stretch dispersive Fourier Transform (TS-DFT) technique based on a fiber chromatic dispersion is a powerful tool for pulse-by-pulse single-shot spectrum measurement for highrepetition rate optical pulses. The distributed feedback laser diode

Real-time Measurements, Rogue Phenomena, and Single-Shot Applications II.
The real-time measurement of fast non-repetitive events is arguably the most challenging problem in the field of instrumentation and measurement. These instruments are needed for investigating rapid transient phenomena such as chemical reactions, fas

Single-shot and long record length spectrum measurements of high-repetition-rate optical pulses are essential for research on nonlinear dynamics as well as for applications in sensing and communication. To achieve a continuous measurements we employ

To improve spectral resolution or capturable pulse-repetition-rate, we introduce a wavelength demultiplexing technique into 1-GHz pulse-by-pulse single-shot spectrum measurement based on time stretch dispersive Fourier Transform. Three times higher r

We present an all optical delay-line radio-frequency (RF) notch filter. The filter exploits cross-gain modulation in a homogeneously broadened laser medium to obtain a negative tap in an optically incoherent system. Applications including moving-targ

Silicon-on-insulator (SOI) technology offers tremendous potential for the integration of optoelectronic functions on a silicon substrate. The authors have demonstrated integrated 3 dB optical directional couplers, a 5/spl times/9 star coupler, and a
