Curves of the correlation coefficient and bit error rate as a function of recording power. Readout results of the TPL signals using 800 nm femtosecond laser beam with the power of 80 μw. The size of the recording region was 40 × 40 μm with 50 × 50 pixels.

... should be pointed out that the TPL intensity signal collected to characterize the polarization dependence in the readout process is not from a single point but an area with a large number of pixels. The detail for detecting the TPL intensity by varying the polarization of the excitation beam can be found in Supplementary information (shown in Figure S3). ...

Context 2

... order to determine the optimal recording energy of the femtosecond laser, we study the relationship between the correlation coefficient (combined with bit error rate) and the various recording powers. Figure 3 shows the correlation coefficient and the bit error rate of different TPL images as a function of recording power. In this example, we use the nanocomposite sample with the LSPR peak at about 800 nm. ...

... is parallel to the aligned orientation of the GNRs embedded in the film. In the readout, the power of the laser is 80 w and remains unchanged in the whole readout process. We choose two polarization orientations to read out the TPL signal, corresponding to parallel and perpendicular to the aligned orientation of the GNRs, respectively. From Fig. 3, we can see that as the recording power increases to 600 W in the case of the polarization is parallel to the aligned orientation of sample, the correlation coefficient increases sharply and then slowly increase to a certain value when the recording power exceeds 600 W. This demonstrates the recording power has to reach a threshold ...

... shown in Fig. 3, when the polarization of the reading laser is perpendicular to the aligned orientation, the correlation coefficient increases sharply when the recording power is above 1800 W, meanwhile the bit error rate reduces gradually. That is because the sample is damaged and loses the polarization dependency by using high laser power. When the ...
