“…For pulses below one picosecond, which roughly corresponds to the carrier thermalization time scale, the saturation energy of SOA and absorber depends on the pulsewidth due to ultrafast gain dynamics. Moreover, in the absorber, it depends on its length since the self-colliding effect helps to bleach the absorption more efficiently [14]. In the absence of ultrafast effects E SOA sat is constant.…”

Abstract:The performance of an external-cavity mode-locked semiconductor laser is investigated both theoretically and experimentally. The optimization analysis focuses on the regimes of stable mode locking and the generation of sub-picosecond optical pulses. We demonstrate stable output pulses down to one picosecond duration with more than 30 dB trailing pulse suppression. The limiting factors to the device performance are investigated on the basis of a fully-distributed time-domain model. We find that ultrafast gain dynamics effectively reduce the pulse-shaping strength and inhibit the generation of femtosecond optical pulses.

“…In this configuration two pulses propagate in the cavity in opposite directions and collide in the SA, saturating it simultaneously. Due to the deep absorber saturation the colliding pulse configuration allows for stable sub-picosecond optical pulse generation [12]. In linear laser configuration this technique is very sensitive to the position of SA, whereas in the ring cavity SA can be located freely.…”

Abstract:In this paper, we present the detailed characterization of a semiconductor ring passively mode-locked laser with a 20 GHz repetition rate that was realized as an indium phosphide based photonic integrated circuit (PIC). Various dynamical regimes as a function of operating conditions were explored in the spectral and time domain. A record bandwidth of the optical coherent comb from a quantum well based device of 11.5 nm at 3 dB and sub-picosecond pulse generation is demonstrated.

“…Since the absorption recovery time sets an upper limit on the achievable repetition rate in a passively mode-locked semiconductor laser, the measured recovery time implies that very high frequency mode locking (e.g., 100 GHz) is possible. Experimentally, semiconductor lasers have been passively mode locked with repetition rates as high as 10 GHz in external cavity lasers, and up to 350 GHz in monolithic cavity mode-locked lasers [18]. The very fast recovery time of waveguide saturable absorbers can be used to suppress multiple pulse formation induced by imperfect antireflection coatings [ 161.…”

Abstract-Mode-locked semiconductor lasers which incorporate multiple contacting segments are found to give improved performance over single-segment designs. The functions of gain, saturable absorption, gain modulation, repetition rate tuning, wavelength tuning, and electrical pulse generation can be integrated on a single semiconductor chip. The optimization of the performance of multisegment mode-locked lasers in terms of material parameters, waveguiding parameters, electrical parasitics, and segment length is discussed experimentally and theoretically.
