چکیده
We demonstrate that quantum dot microdisk lasers are able to operate under continuous wave current injection at 100 o C. We also present a novel method for increasing a side mode suppression ratio in microdisk lasers.

Ultrasmall microdisk and microring lasers based on InAs/InGaAs/GaAs quantum dots
UNLABELLED Ultrasmall microring and microdisk lasers with an asymmetric air/GaAs/Al0.98Ga0.02As waveguide and an active region based on InAs/InGaAs/GaAs quantum dots emitting around 1.3 μm were fabricated and studied. The diameter D of the microrings and microdisks was either 2 or 1.5 μm, and the inner diameter d of the microrings varied from 20% to 70% of the outer diameter D. The microring wi...
متن کاملLasing characteristics of InAs quantum dot microcavity lasers as a function of temperature and wavelength.
A Strong temperature dependence of microdisk lasers and photonic crystal nanocavity lasers with InAs quantum dot active regions is reported. These lasers operate at 1.3 microm at room temperature under optical pumping conditions. T(0, microdisk) = 31 K. T(0, photonic crystal nanocavity) = 14 K. The lasing threshold dependence on the lasing wavelength is also reported. We observe a minimum absor...
متن کاملInAs/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...

Optical characterization of AlGaAs microdisk resonant cavities with a quantum dot active region is presented. Direct passive measurement of the optical loss within AlGaAs microdisk resonant structures embedded with InAs/ InGaAs dots-in-a-well sDWELLd is performed using an optical-fiber-based probing technique at a wavelength sl,1.4 mmd that is red detuned from the dot emission wavelength sl,1.2...

We report growth and room temperature continuous wave operation of InAs quantum-dot microdisk lasers grown on nominal (001) silicon substrates. The active structure containing five layers of InAs/GaAs quantum dots was grown by MBE on a GaAs-on-v-grooved-Si (GoVS) template produced by MOCVD. Microdisk lasers with 4 μm diameters showed continuous wave lasing at room temperature with thresholds on...
