Dual-wavelength mode-locked quantum-dot laser, via ground and excited state transitions: experimental and theoretical investigation.

چکیده
We report a dual-wavelength passive mode locking regime where picosecond pulses are generated from both ground (lambda = 1263 nm) and excited state transitions (lambda = 1180 nm), in a GaAs-based monolithic two-section quantum-dot laser. Moreover, these results are reproduced by numerical simulations which provide a better insight on the dual-wavelength mode-locked operation.

Simulation and Design of Quantum-Dot Lasers
Simultaneous pulse generation from ground state and excited state transitions in a two-section quantum-dot laser is studied via a finite-difference travelling-wave model; design rules to obtain stable dual-wavelength mode-locking regime over a wide range of bias current and voltage are proposed. Quantum-dot laser; passive mode-locking; two-state lasing; finite-difference travelling-wave model;

The frequency behavior of the tunnel injection quantum dot vertical cavitysurface emitting laser (TIQD-VCSEL) is investigated by using an analyticalnumericalmethod on the modulation transfer function. The function is based on therate equations and is decomposed into components related to different energy levelsinside the quantum dot and injection well. In this way, the effect of the tunnelingpr...

We present an investigation of passive and hybrid mode-locking in Fabry-Pérot type two-section InAs/InP(100) quantum dot lasers that show dual wavelength operation. Over the whole current and voltage range for mode-locking of these lasers, the optical output spectra show two distinct lobes. The two lobes provide a coherent bandwidth and are verified to lead to two synchronized optical pulses. T...
متن کاملInvestigation of quantum dot passively mode-locked lasers with excited-state transition.
Monolithic passively mode-locked quantum dot lasers with excited-state transition were investigated in a broad operating range without ground-state lasing. Optical and electrical characteristics of these mode locked lasers were studied in detail at different levels of injection current and absorber bias. Very different behaviors in the evolution of the hysteresis, the optical spectra and the ev...
متن کاملTheoretical and Experimental Investigation of Quantum Dot Passively Mode Locked Lasers for Telecomm and Biomedical Applications
This thesis is focused on the experimental and theoretical study of novel quantum dot passively mode locked lasers. The motivation behind this endeavour was the fundamental need, of many scientific areas, for high power, ultra-short and time stabilized optical pulses, generated directly from highly integrated laser devices. Such devices could allow the study of ultra-fast chemical and physical ...
