Pulse Characteristics of Passively Mode- Locked Quantum Dot Lasers (postprint)
Interest in quantum dot mode-locked lasers (QD MLLs) has grown in recent years since their first demonstration in 2001 as applications for optical time domain multiplexing, arbitrary waveform generation, and optical clocking are anticipated. Ultrafast pulses below 1 ps have been reported from QD MLLs using intensity autocorrelation techniques, but so far detailed characterization examining the ...
متن کاملQuantum - dot external - cavity passively mode - locked laser with high peak power and pulse energy
An InAs quantum-dot external-cavity passively mode-locked laser with an operation wavelength of 1.27 μm is demonstrated, based on a two-section quantumdot superluminescent diode with bending ridge waveguide and a 96% output coupler. Stable mode-locking with an average power up to 60 mW was obtained at a repetition frequency of 2.4 GHz. This performance corresponds to a 25-pJ pulse energy obtain...
متن کاملRoom temperature passive mode-locked laser based on InAs/GaAs quantum-dot superlattice
Passive mode-locking is achieved in two sectional lasers with an active layer based on superlattice formed by ten layers of quantum dots. Tunnel coupling of ten layers changes the structural polarization properties: the ratio between the transverse electric and transverse magnetic polarization absorption coefficients is less by a factor of 1.8 in the entire electroluminescence spectrum range fo...
متن کاملOptical and RF stability transfer in a monolithic coupled-cavity colliding pulse mode-locked quantum dot laser.
We report a novel quantum dot based laser design where a stable high-Q master laser is used to injection lock a passively mode-locked monolithic colliding pulse slave laser. Coupling between the crossed orthogonal laser cavities is achieved through a common monolithically integrated saturable absorber, which results in the locking and hence reduction of the timing jitter as well as the long-ter...
متن کاملFrequency comb generation by CW laser injection into a quantum-dot mode-locked laser.
We report on frequency comb generation at 1.5 μm by injection of a CW laser in a hybridly mode-locked InAs/InP two-section quantum-dot laser (HMLQDL). The generated comb has > 60 modes spaced by ∼ 4.5 GHz and a -20 dBc width of > 100 GHz (23 modes) at > 30 dB signal to background ratio. Comb generation was observed with the CW laser (red) detuned more than 20 nm outside the HMLQDL spectrum, spa...
