Mechanism for enhanced wavelength tuning in gain-levered InP quantum dot lasers
نویسندگان
چکیده
Peak gain wavelength tuning via the gain-lever effect is demonstrated in segmented contact InP quantum dot Fabry–Perot lasers. A tuning range of 6.5 ± 0.1 nm was recorded in the lasing spectra of a 1.9 mm long broad area device operating at 22°C. The authors clarify the nature of the tuning mechanism and identify the critical material and device parameters that determine the limits of the wavelength tuning range.

InAs/InP(100) quantum dot laser with high wavelength stability
Introduction: The lasing wavelength of a semiconductor laser inevitably changes with varying the operation temperature, which is, however, not desirable for applications requiring specific and stable light wavelength. Thus, laser diodes with wavelength insensitive to temperature are fascinating and can drastically ease the critical requirements on precise temperature control. The quantum dot (Q...
متن کاملDual-wavelength passive and hybrid mode-locking of 3, 4.5 and 10 GHz InAs/InP(100) quantum dot lasers.
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...

We report a single layer InAs/InP (100) quantum dot (QD) laser operating in continuous wave mode at room temperature on the QD ground state transition grown by metal organic vapor phase epitaxy. The necessary high QD density is achieved by growing the QDs on a thin InAs quantum well (QW). This QDs on QW laser exhibits a high slope efficiency and a lasing wavelength of 1.74 μm.

This article reviews the recent progress in the growth and device applications of InAs/InP quantum dots (QDs) for telecom applications. Wavelength tuning of the metalorganic vapor-phase epitaxy grown single layer and stacked InAs QDs embedded in InGaAsP/InP (1 0 0) over the 1.55-mm region at room temperature (RT) is achieved using ultra-thin GaAs interlayers underneath the QDs. The GaAs interla...
