چکیده

A record broadly tunable high-power external cavity InAs/GaAs quantum-dot diode laser with a tuning range of 202 nm (1122 nm-1324 nm) is demonstrated. A maximum output power of 480 mW and a side-mode suppression ratio greater than 45 dB are achieved in the central part of the tuning range. We exploit a number of strategies for enhancing the tuning range of external cavity quantum-dot lasers. Different waveguide designs, laser configurations and operation conditions (pump current and temperature) are investigated for optimization of output power and tunability.

Low threshold current and widely tunable external cavity lasers with chirped multilayer InAs/InGaAs/GaAs quantum-dot structure.

Low threshold and widely tunable InAs/GaAs quantum-dot lasers are implemented with grating-coupled external-cavity arrangement. Throughout the tuning range of 130 nm, from 1160 to 1290 nm, the threshold current density is not more than 0.9 kA/cm2 and no noticeable threshold jump is observed. For a shorter-cavity device, the injection current is kept at a record low value of 90 mA but the tuning...

Monolithically integrated twin ring diode lasers with quantum-dot active region

Optoelectronic integrated circuits incorporating twin ring diode lasers with InAs/InGaAs/GaAs quantum-dot active region have been fabricated and characterized. Directional control and unidirectional operation of ring diode lasers are demonstrated by forward biasing an S-section waveguide incorporated within the ring cavity. Mode-beating spectra from individual ring diode lasers are observed at ...

Quantum - 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...

Extremely low room-temperature threshold current density diode lasers using InAs dots in In0.15Ga0.85As quantum well

Introduction: It has been predicted that the threshold current density of quantum dot lasers should be lower than that of quantum well lasers due to the reduction of density of states [1]. In particular, efforts have been made in the past few years to reduce the threshold current density of quantum dot lasers on GaAs substrates [2, 3]. A recently developed approach is to put the InAs dots in a ...

Coupled strained-layer InGaAs quantum-well improvement of an InAs quantum dot AlGaAs–GaAs–InGaAs–InAs heterostructure laser

Data are presented showing that, besides the improvement in carrier collection, it is advantageous to locate strain-matching auxiliary InGaAs layers @quantum wells ~QWs!# within tunneling distance of a single-quantum-dot ~QD! layer of an AlGaAs–GaAs–InGaAs–InAs QD heterostructure laser to realize also smaller size QDs of greater density and uniformity. The QD density is changed from 2310/cm for...
