Investigation of microdisk and microring lasers based on InGaAs/GaAs QWDs by the interferometry method
The scanning interferometer method is used to measure the line width of microdisk
and microring lasers with a diameter of the resonator ranging from 15 to 50 μm and active area
based on InGaAs/GaAs quantum well-dots. Above the threshold, the spectral width of the line
did not exceed 3 pm for all samples under study.
