Correction to “2D ReS2/3D Bi2O2Se Homo-Heterojunction Photodetector Toward Near-Infrared Polarization Sensitive Detection and High Sensitivity Communication”

Abstract

We regret that, recently, one error was found in the article.

In the initially published version of the article, the text annotations in Figure 4C and its corresponding mentions in the main text use incorrect descriptions.

The revised version of the corresponding description is presented below.

In light of this, we propose the capacity of a polarization-sensitive photodetector to facilitate secure communication through the encoding of information within polarization states (see Figure 4C). The digital message “1 011 001” is divided into individual bits. Each bit is subsequently associated with a specific polarization state, utilizing the pre-established encryption key (Bit 0: Horizontal linear polarization (0°); Bit 1: Vertical linear polarization (90°)). The Polarization Modulator is responsible for dynamically altering the laser's polarization state in accordance with the encryption key. The polarization-sensitive photodetector subsequently measures the polarization state of the incoming light. For each bit, it determines whether the light is horizontally linear polarized (0°) or vertically linear polarized (90°).

The corrections do not affect any of the conclusions of this article. We apologize for any inconvenience caused. We would like to correct the errors and provide the corrected image below.

We apologize for the careless errors.

The corrected Figure 4C and updated Figure 4 is shown as follows.
