摘要

光加密技术通过调制光的波长、振幅、偏振或轨道角动量来保证加密系统的安全性。在这项工作中，典型的窄带隙半导体GaSb纳米线（NW）通过调制光探测波长被证明是红外光谱加密的竞争候选人。GaSb NW的带隙被控制在0.72 ~ 1.28 eV之间，有利于1550 ~ 785 nm的可调光探测波长范围。因此，采用四种不同带隙的gab NW实现了红外光谱加密。可控的带隙是由于在易于操作和低成本的化学气相沉积过程中成功地生长了GaNSb三元合金。最后，将红外光谱加密作为门上的密码锁进行演示，涵盖了高级密码学的需求。研究中的GaSb NW红外光谱加密有望实现下一代军用或高安全性加密。

Tunable Photodetection Range of GaSb Nanowires for Infrared Spectral Encryption.

The optical encryption technique is promising for the security of an encryption system by modulating the wavelength, amplitude, polarization, or orbital angular momentum of light. In this work, the typical narrow bandgap semiconductor of GaSb nanowire (NW) is demonstrated as a competitive candidate for infrared spectral encryption by modulating the photodetection wavelength. The bandgap of GaSb NW is controlled from 0.72 to 1.28 eV, benefiting the tunable photodetection wavelength range of 1550-785 nm. As a result, an infrared spectral encryption is realized by a GaSb NW with four different bandgaps. The controlled bandgap results from the successful growth of the GaNSb ternary alloy during the easily handled and low-cost chemical vapor deposition process. In the end, infrared spectral encryption is demonstrated as a code lock of a door, covering advanced cryptographic needs. The as-studied GaSb NW infrared spectral encryption promises next-generation military or high-security encryption.
