Spectral line‐by‐line shaping is a key enabler towards optical arbitrary waveform
generation, which promises broad impact both in optical science and technology. In this …

We report our recent studies on nonlinear processing of optical signals using a 35-cm highly
nonlinear bismuth oxide fiber (Bi-NLF). Our findings are based on self-phase modulation …

We propose the simple pulse source, in which the pulses generated by large-signal directly
modulated laser diode are phase-modulated, and then compressed into short pulses by an …

We experimental demonstrate stable, simple and pulse width-tunable 40 GHz short time
window generation using a dual parallel Mach-Zehnder modulator (DPMZM) driven simply …

An all-optical signal processing scheme coupling wavelength conversion and NRZ-to-RZ
data format conversion with pulsewidth tunability into one by combination of SOA-and fiber …

We propose a novel all-optical format conversion scheme from the return-to-zero (RZ) to non-
return-to-zero (NRZ) based on a single dispersion-flattened highly nonlinear photonic crystal …

An absorption-adjustable graphene saturable absorber is used in a simple fiber laser
system for an active control of the pulse-width of optical pulses. Such a saturable absorber is …

We demonstrate a method for tunable optical return-to-zero (RZ) pulse generation with large
tunable wavelength range (1532/spl sim/1562 nm) and pulsewidth range (/spl sim/3-50 ps) …

A novel scheme of a highly stable dual-wavelength short optical pulse source (SOPS) based
on a dual-loop optoelectronic oscillator (OEO) with two wavelengths is demonstrated. The …

A wavelength-shift-free adjustment of pulsewidth in return-to-zero on-off keyed signals is
demonstrated by means of adiabatic pulse compression in distributed Raman amplification …
