The quest towards the integration of ultra-fast, high-precision optical clocks is reflected in the
large number of high-impact papers on the topic published in the last few years. This interest …

Nonlinear photonic chips can generate and process signals all-optically with far superior
performance to that possible electronically—particularly with respect to speed. Although …

We demonstrate a novel mode locked ultrafast laser, based on an integrated high-Q
microring resonator. Our scheme exhibits stable operation of two slightly shifted spectral …

Nonlinear optical effects are typically weak and enhancement techniques are often required
for practical applications. Here we introduce a method to enhance such effects by …

Ultrashort pulsed lasers, operating through the phenomenon of mode-locking, have had a
significant role in many facets of our society for 50 years, for example, in the way we …

High-repetition-rate pulses have widespread applications in the fields of fiber
communications, frequency comb and optical sensing. Here, we have demonstrated high …

We study theoretically and experimentally the so-called self-induced modulational instability
laser and show that the passive mode-locking mechanism that is at play in this laser relies …

Searching for an ultrahigh-repetition-rate pulse on the order of hundreds of gigahertz (GHz)
is still a challenging task in the ultrafast laser community. Recently, high-quality silicon/silica …

We provide a perspective review over the recent development of short-pulsed Raman fiber
lasers (RFLs), which can provide laser emissions with flexible wavelengths for a variety of …

Ultrafast lasers generating high-repetition-rate ultrashort pulses through various mode-
locking methods can benefit many important applications, including communications …
