In this work, we announce a new 3-D jerk system and show that it is chaotic and dissipative with the calculation of the Lyapunov exponents of the system. By performing a detailed bifurcation analysis, we observe that the new jerk system exhibits Hopf bifurcations. It is also shown that the new jerk system exhibits multistability behaviour with two coexisting chaotic attractors. An electronic circuit simulation of the jerk system is built using Multisim. Finally, we design a new approach to image encryption as a cryptographic application of our chaotic jerk system. The simulation outcomes prove the efficiency of the proposed encryption scheme with high security.

“…Gain Switching generates short optical pulses when the device is switched with currents from below threshold to a higher current above threshold. Optimum short pulse generation in QCLs by gain switching is presented in [6][7][8]. The same is analyzed for dual wavelength QCLs [9].…”

This article investigates the performance of a free space optical (FSO) communication link by incorporating the device parameters that influence the optical output power of the quantum cascade laser (QCL). The transmitter side of the FSO link consists of gain-switched QCL operating at 9 µm. Short optical pulses possessing minimum full width half maximum (FWHM) and peak power as a result of ON-OFF keying are transmitted into the channel. The pulses are attenuated by medium bound losses and reach the receiver which employs quantum well infrared photodetector operating in the same wavelength. Average signal-to-noise ratio (SNRavg), bit error rate (BER) and Channel Capacity are computed for the FSO link for all the variations in the device parameters namely optical confinement factor (Γ), spontaneous emission factor (β) and mirror reflectivity (R). The combination of device parameters that gives the best link performance is assessed. From the analysis it is observed that, under minimum FWHM condition, QCL with Γ = 0.32 provides the best average SNR of 4.04 dB, lowest BER of 13.02 × 10−2 and maximum capacity of 1.82 bps Hz−1. When peak power is the constraint, QCL with mirror reflectivity of Γ = 0.45 provides the best average SNR of 24.78 dB, lowest BER of 7.75 × 10−35 and a peak capacity of 8.24 bps Hz−1.
