“…Femtosecond pulses with multi-GHz repetition rates have been demonstrated from a range of Er-doped fiber lasers around 1.5 μm with average powers reaching 27 mW, using SESAMs or carbon nanotubes as mode-locking devices [15][16][17][18]. A femtosecond (~206 fs) Yb-doped fiber laser at 1025 nm has also been demonstrated with a PRF of 3 GHz and an average power up to 53 mW [19].…”

Abstract:We demonstrate passively mode-locked Yb 3+ -doped glass waveguide lasers in a quasi-monolithic configuration with a maximum pulse repetition frequency up to 15.2 GHz. A semiconductor saturable absorber mirror (SESAM) is used to achieve stable mode-locking around 1050 nm with pulse durations as short as 811 fs and an average power up to 27 mW. Different waveguide samples are also employed to deliver pulses with repetition rates of 4.9 GHz, 10.4 GHz and 12 GHz with an average power of 32 mW, 60 mW and 45 mW, respectively. The group velocity dispersion control in the cavity is provided by changing the gap between the SESAM and the waveguide end-face to facilitate a soliton mode-locking regime. Ferrari, and A. K.

“…Repetition rates of up to 19 GHz have been achieved [16] with an average power < 1 mW, and a power of 50 mW was reached for a repetition rate of 3 GHz [17] near 1m using semiconductor saturable absorber mirrors (SESAMs) for passive mode-locking. Mode-locked fibre lasers with a similar architecture have also been operated near 1.5 m with repetition rates up to 3 GHz and power levels of a few milliwatts [18].…”

Abstract. We report a passively mode-locked, diode-pumped waveguide laser operating in the 1.5 m spectral region using a quantum dot SESAM as the saturable absorber element. A repetition rate of up to 6.8 GHz and an average power as high as 30 mW is obtained during mode-locked operation. Minimum pulse duration of 2.5 ps is produced at a wavelength of 1556 nm. The repetition rate of the source was tuned by more than 1 MHz by changing the pump power, demonstrating a possible route towards integrated pulse repetition rate stabilisation.

“…Thus, according to Table 1, this To make these low jitter sources useful for photonic ADCs, they must be scaled to higher repetition rates (GHz), miniaturized and eventually even made available as integrated photonic devices. A first result towards this goal was achieved recently with the demonstration of a miniaturized fiber laser which consisted only of 3 cm long highly-doped Er fiber with a saturable absorber and output coupler butt-coupled to it [10]. This laser generates 500 fs pulses at 3.2 GHz repetition rate with a timing jitter of less than 20 fs in the range of [10 kHz, 10 MHz].…”

Progress in developing high speed Analog-to-Digital Converters (ADCs) occurs rather slowly due to the inherent jitter in electronic sampling and the difficulty in integrating low noise microwave sources. Currently, this electronic jitter is on the order of 100 femtoseconds in the most advanced CMOS circuitry. Advances in femtosecond lasers and laser stabilization have led to the development of sources of ultrafast optical pulse trains that show timing jitter on the level of a few femtoseconds over the time spans of typical sampling windows and can be made even smaller in the future. This paper reviews the progress made towards low noise femtosecond lasers, its jitter characterization, and its application in high-speed, high-resolution analog-to-digital conversion.
