Figure 5.

Simulation and measurement results of the angle sensing detector for various polarizations and planes of incidence. (a–c) The response of the detector for (a) $\widehat{x}$-polarized, (b) $ŷ$-polarized, and (c) incoherent polarizations when the wave is incident within the y − z plane. Here, the angle of incidence was measured from the z axis. + and − θ values are defined in part (g). (d–f) The results for (d) $\widehat{x}$-polarized, (e) $ŷ$-polarized, and (f) incoherent polarizations when the wave is incident from a plane that makes a 45° angle with the x axis. + and − θ values are defined as shown in part (h). Error bars in these figures are the results of the measurements of few different devices, and also multiple measurements of a single device with different power of the laser.
