From: Spin photocurrent spectra induced by Rashba- and Dresselhaus-type circular photogalvanic effect at inter-band excitation in InGaAs/GaAs/AlGaAs step quantum wells

Figure 1

The schematic diagram of the experimental geometries and the spectra of the normalized CPGE current. The schematic diagram for geometries CPGE-I (a) and CPGE-II (b and c). The spectra of the normalized CPGE current obtained by geometry CPGE-II at different angles of incidence (d). The thin lines indicate the sum of j R and j D by the geometry shown in (b), and the thick lines indicate the difference of j R and j D obtained by the geometry shown in (c). All of the spectra are shifted vertically for clarity.
