In this work, the concept of optical identification (OI) based on physical unclonable functions
is introduced for the first time, to our knowledge, in optical communication systems and …

In this review paper, we discuss the properties and applications of photonic computing and
analog signal processing. Photonic computational circuits have large operation bandwidth …

With the progress of science and technology, optical structure materials and devices
developed based on subwavelength artificial micro-nanostructures, such as metamaterials …

The concept of multi-homodyne coherent detection is used for stealth and secured optical
communications, demonstrating a transmission rate of 20 Gbps under negative (in dB) …

Amplified spontaneous emission (ASE) light is the most natural optical carrier to hide a
message in the existing optical networks at photonic layer. To enhance the anti-intercept …

The physical layer transmission security is a promising technology against security threats.
As an effective supplement to the encryption strategy, steganography has received …

We propose and experimentally demonstrate a secure quantum noise stream cipher
transmission system that integrates key generation and distribution. At the stage of carrier …

To provide secure and covert transmission for optical communication system at the same
time, a quantum-noise stream ciphered optical stealth communication approach is proposed …

We introduce the concept of optical fingerprint in optical communications and networks. In
the assumption of being able to read devices', sub-systems', and systems' fingerprint, a new …

We report a real-time 150 kbps stealth transmission within public optical communication of
10 Gbps dual polarization QPSK. The stealth data is modulated onto the frequency tuning …
