a Emission spectra of a 15-μm-aperture MC device under different injection currents at 77 K. b Measured emission intensities of gain peak and FP1 at 77 K as a function of injection current. Emission intensities of (c) gain peak and (d) FP1 in log scale vs injection current (linear scale) at 77 K. Black fitting curves correspond to the intensity variation vs injection current
