FIG. 1.

(Color online) (a) Typical TRSHG measurement of InN sample, where AC denotes the autocorrelation signal to define the zero delay time. (b) Oscillatory component is extracted from the slow time-varying background by taking the time differential of the TRSHG curve, (c). Fourier transform of the oscillatory component reveals the coherent phonon spectroscopy of InN.

(Color online) (a) Coherent mode shows a clear frequency shift in the four pump-power dependent coherent phonon spectra with offset. The photoexcited plasma densities are set as follows: (A) , (B) , (C) , and (D) , respectively. (b) Spontaneous Raman spectrum is taken for comparison.

FIG. 3.

(Color online) Measured mode frequencies are plotted as a function of the plasma density (open symbols) for three different InN samples. The lines show the lower bound (with ), best fitting (with ), and upper bound (with ) of calculated mode frequency curves by solving the InN dielectric response function.
