Subject: Measurement of the reflectivity, EQE, and IQE of the PD without glass window  

The glass window of the PD was removed and is placed in our shelf.

The reflectivity, EQE, and IQE of the PD were measured without the glass window as shown in following figures in the same setup as the measurements of the PD with glass window (see also elog2019, elog2020, and elog2022).

The laser power incident to the PD was 11.4 +/- 0.1 mW.

Fig. 1 Measured reflectivities of the PD without the galss window for P-pol and S-pol.
Fig. 2 Determined EQEs and IQEs of the PD without the galss window for P-pol and S-pol.
Fig. 3 Zoomed version of Fig. 2.
