“…Optical signal sources capable of generating stable ultra -short pulse trains at high repetition rates and with a tuning range as wide as possible are key elements for these novel photonic networks that may combine wavelength division multiplexing (WDM) and optical time domain multiplexing (OTDM) transmission techniques [1]. Short pulse ultrafast lasers are also necessary for the performance of ultrahigh speed, all -optical logic experiments and the demonstration of alloptical Boolean functions such as AND and XOR [2], [3].…”

A theoretical study of a high repetition rate laser source based on a novel modelocking technique is presented. This technique relies on the fast saturation and recovery of a semiconductor optical amplifier induced by an external optical pulse and has been used to obtain 4.3 ps pulses at 20 GHz. A numerical model of the fiber ring laser has been developed describing the mode -locking process in the laser oscillator and providing solutions for the steady -state mode -locked pulse profile. The critical parameters of the system are defined and analyzed and their impact on the formation of the mode -locked pulses is examined. The comparison between the theoretical results and the experimental data reveals very good agreement and has allowed the optimization of the performance of the system in terms of these parameters.

“…Photonic crystal fiber has been remarkably successful in supercontinuum generation (SCG) due to the feasibility of controlling the dispersion and reducing the mode area by engineering its air-hole geometry [2][3][4]. Interest in SCG has been driven by applications including frequency combs [5,6], optical coherence tomography [7], and wavelength division multiplexing [8,9]. In the past few years, SCG has also been investigated in several chip-based systems, including silicon photonic nanowires [10][11][12], chalcogenide waveguides [13,14], and silicon nitride (Si 3 N 4 ) waveguides [15,16].…”

Supercontinuum generation is demonstrated in an on-chip silica spiral waveguide by launching 180 fs pulses from an optical parametric oscillator at the center wavelength of 1330 nm. With a coupled pulse energy of 2.17 nJ, the broadest spectrum in the fundamental TM mode extends from 936 to 1888 nm (162 THz) at −50 dB from peak. There is a good agreement between the measured spectrum and a simulation using a generalized nonlinear Schrödinger equation.

A low-loss silica spiral waveguide is used for demonstrating on-chip supercontinuum generation. The broadest measured spectrum spans an octave (936 -1888 nm) at -50 dB from peak when 2.17 nJ pulses are launched. [5], and wavelength division multiplexing [6]. In such context, on-chip waveguides for SCG would bring important functionalities of photonic integrated circuits. Although silica has a small Kerr coefficient of 2.6 × 10 -20 m 2 W -1 , it has a much lower linear loss compared to other materials, a crucial factor for the success of fiber based devices. Recently, a chip-based, silica waveguide functioning as a low-loss optical delay line was reported [7]. Here, the ability for SCG using the waveguide is tested. A silica waveguide with a total physical path length of 3.5 m consisting of four, cascaded, double-interleaved Archemidian spirals is used in the experiment (Fig. 1a). The outer radius of each spiral is 7.0 mm and the chip size is 2.5 cm × 6.9 cm. A pulse train with 80-MHz repetition rate and FWHM of 180fs is launched from an optical parametric oscillator (Spectra-Physics OPAL). The energy and the polarization of the pulse are controlled using a variable neutral density filter and a half-wave plate, as shown in Fig. 1b. An objective lens with 12-mm focal length is used to free-space couple the light into the waveguide. At the waveguide end, a cleaved multimode fiber is closely
