Analysis of the lasing characteristics of InGaAs/GaAs WGM microlasers

P. 012096.
Kryzhanovskaya N., Moiseev E., Zhukov A. E., Maksimov M. V.

We present an analysis of spectral and threshold characteristics of InGaAs/GaAs
quantum well-dot microdisk laser operated under cw current injection at room temperature
without external cooling. The experimental values of the threshold current for the disk and
ring microlasers are compared. We observe that the threshold current can be significantly
decreased in devices with large diameters (more than 30 m) by using the ring geometry
