a RT spectra of a 15-μm-aperture MC device under different injection currents. b RT emission spectrum of a 15-μm-aperture MC device operated at 0.1 μA current injection. Green dashed lines represent the fitting curves of each transverse optical mode, and red dashed lines depict the summarized fitting curves. c Emission intensities and d linewidths of gain peak and FP modes extracted from the measured RT spectra as a function of injection current
