Background:

Controlling lasing-mode oscillations in laser cavities is crucial for laser physics and applications.
Whispering-gallery mode (WGM) resonators offer potential for miniaturized laser devices.

Purpose of the Study:

To realize an electrically driven single-mode microlaser.
To engineer lasing-mode oscillations using a novel material structure.

Main Methods:

Fabrication of a microlaser device using gallium-doped zinc oxide microwires (ZnO:Ga MW) coated with platinum nanoparticles (PtNPs).
Incorporation of magnesium oxide (MgO) and platinum (Pt) buffer layers on a p-type Gallium Nitride (GaN) substrate.
Utilizing whispering-gallery mode (WGM) resonance within the ZnO:Ga MW for lasing.

Main Results:

Achieved single-mode lasing at a wavelength of 390.5 nm with a narrow linewidth of 0.18 nm.
Evaluated cavity quality factor (Q) to be approximately 2169.
Demonstrated that PtNPs can engineer multimode lasing actions, enabling single-mode operation even in larger microwires.

Conclusions:

The developed device structure effectively integrates the electron-hole recombination region, gain medium, and optical microresonator.
The use of Pt and MgO buffer layers optimizes band alignment and current injection for improved device performance.
This work provides a viable scheme for developing single-mode microlasers based on one-dimensional semiconductor microwires.
