“…Another possibility of enhancing pulse train stability is the application of non-frequency selective external feedback. The stabilization potential of a combination of a passively mode-locked semiconductor laser with an optical fiber cavity and non-frequency selective mirror has yielded picosecond pulses with high peak power under continuous current injection [1], [7], [8]. An antireflective coated InGaAsP-InP 1.3 m two-section laser with proton-bombarded trench section in a passive external mirror cavity resulted in passive mode-locking at harmonics of the cavity round-trip time [9].…”

Abstract-We have investigated experimentally the pulse train (mode beating) stability of a monolithic mode-locked multi-section quantum-dot laser with an added passive auxiliary optical fiber cavity. Addition of the weakly coupled ( 24 dB) cavity reduces the current-induced shift of the principal peak in the RF spectrum (the effective pulse repetition frequency) by more than an order of magnitude, from 39 5 to 2 3 kHz/mA. The rms timing jitter of the pulse train is simultaneously reduced from 1.4 to 0.9 ps.

Optical self seeding feedback techniques can be used to improve the noise characteristics of passively mode-locked laser diodes. External cavities such as fiber optic cables can increase the memory of the phase and subsequently improve the timing jitter. In this work, an improved optical feedback architecture is proposed using an optical fiber loop delay as a cavity extension of the mode-locked laser. We investigate the effect of the noise reduction as a function of the loop length and feedback power. The well known composite cavity technique is also implemented for suppressing supermode noise artifacts presented due to harmonic mode locking effects. Using this method, we achieve a record low radio frequency linewidth of 192 Hz for any high frequency (>1 GHz) passively mode-locked laser to date (to the best of the authors' knowledge), making it promising for the development of high frequency optoelectronic oscillators.
