From: Polarized photoreflectance and photoluminescence spectroscopy of InGaAs/GaAs quantum rods grown with As2 and As4 sources

Figure 4

Room temperature linearly polarized photoluminescence spectra split into TE and TM modes for QR35 samples. The samples were grown using As4(a, c) and As2(b, d) sources. PL spectra are normalized to the most intense peak of the GS transitions in the InGaAs QRs. Circles indicate the optical anisotropy, represented by the degree of polarization, DOP.
