In single-photon excitation condition, ZnO lasing generally originates from the F-P cavity by two end facets of nano/microrod [1, 4], or WGM cavity by six sides [5, 18].
At higher excitation intensity, the lasers were mainly generated from EHP emission, and the laser positive feedback was provided by F-P cavities by two opposite sides.

The classification accuracy and bit rate of STF-P were better than those of F-P when 1-16 numbers of trials were used for averaging.
The classification accuracy and bit rate of STF-P were significantly higher than those of F-P (t = 2.89, p < 0.05, df = 9 for classification accuracy, t = 4.03, p < 0.05, df = 9 for bit rate).
This study aimed to survey whether any difference would be found between STF-P in which the subject could see the target character during the time the stimuli were on and F-P in which the target character was concealed during the time the stimuli were on.
In the present study, the STF-P elicited larger N200 component than the F-P. On the one hand, semitransparent face stimuli may lead to a high mismatch, thereby resulting in a large N200.
Since the significant difference of N400 between the first and third offline run was found in the F-P while not in the STF-P (see Figures 4(e) and 4(f)), it indicated that STF-P contained less repetition effects compared to the F-P.
In this study, the averaged classification accuracy and bit rate of the sTf-P were 95.0%, 42.6bit/min, while those of the F-P were 91.9%, 38.0bit/min, and were 3.1%, 4.6bit/min, higher than those of the F-P.
In this study, we measured the performance of STF-P and F-P on BCI.
