This paper presents novel optical encryption and decryption systems using a semiconductor optical amplifier at 40 Gb/s. Proposed scheme exploits cross-phase modulation phenomenon in SOA. Our design is mainly based on SOA Mach-Zehnder interferometer structure, optical couplers, CW light, and EDFA. We demonstrate that our implementation is more feasible than conventional SOA-MZI encryption system, where only single optical pulse source is used. Experimental evaluation using eye diagrams shows robustness of our proposed encryption decryption system against eavesdropping.

“…After defining MPD based spatial demodulation for optical communications, we design an all-optical hardware based symmetric-key cryptography system, for the first time, by exploiting only passive MPD design, without any software based decoding complexity. There are various all-optical encryption/decryption mechanisms utilizing symmetric or private-key based mechanism by using spectral shuffling [29] and all-optical logic gates [30], [31]. However, MPD based architecture is not exploited.…”

Spatial light modulation enhances capacity of optical communications by modulating spatial amplitude, phase and polarization degrees of freedom with recent success of orbital angular momentum based architectures. There is a hardware challenge to demodulate large symbol families or high order symbols requiring a general design of spatial light demodulation. Multi-plane diffraction (MPD) recently introduced for improving spatial modulation capabilities in free space optical channels promises utilization at the receiver side as a demodulator. In this article, we theoretically model, numerically simulate and experimentally implement spatial light demodulation based on MPD. Numerical simulations and experimental implementations verify capabilities of MPD for increasing inter-symbol distances at the detector front-end. We obtain approximately two times improvement compared with direct detection for basic design including three diffraction planes as a proof-of-concept and improved performance with increasing number of diffraction planes compared with state-of-the-art single-plane diffraction (SPD) based interferometric receivers. Besides that, we perform, for the first time, experimental implementation of MPD based spatial light modulation. In addition, symmetric-key cryptography application of the proposed system is theoretically presented with low decoder complexity while numerical simulations promise high performance security against intruders. MPD based design is practically applicable and promising for diverse optical architectures including both communications and cryptography as a low-cost, low hardware complexity, passive and high performance design.

“…Use of optical logic gates (optical XOR gates) is central to the development of designing circuits which can ensure secure transmission of data. Optical communication at a speed of 10 GB/s using encryption and decryption circuits was demonstrated by Jung [2]. The security of optical signal relies mainly on the physical properties of the signal and not on the computational complexity as in software systems.…”

This project proposes the design of ultrafast communication circuit which can enable the high speed secured data transmission at 50 Gb/s and 100 Gb/s by the use of distributed Raman amplifier, EDFA (Erbium – doped fiber amplifier), filter, single mode fiber along with Fiber Bragg Grating (FBG) and attenuators. The simulation of the suggested optical circuit involves the use of parameters of Raman amplifier and EDFA and other components included in the optical structure. The design also includes the use of encryption and decryption techniques to ensure secured communication. Thus, realization of these circuits at 50 Gb/s and 100 Gb/s will enable the future optical communication applications for ultrafast data transmission to large distances.
