Key Points

This research aims to explore the characteristics of room temperature microlasers using a quasi-planar geometry.
Planar microcavity structure grown using molecular-beam epitaxy.
Lasing threshold assessed at room temperature (300 K) and different pump power levels.
Evaluation of mode energy shift in relation to pump power.
Single-mode lasing observed at 960 nm for pillars of 15 μm diameter.
Lasing threshold approximately 30 mW at 300 K.
Mode energy shift of approximately 1 meV observed when pump power increased to 2.7 times threshold.

Implication

Investigates single-mode lasing in microlasers, highlighting energy shifts and thresholds.
