“…Different intensity modulation formats such as RZ, NRZ, and CSRZ are simulated using HNLF of 2 km length [11], and it is found that CSRZ has the best Q-factor considering all three intensity modulation formats. The differential phase modulation format DPSK has been reported using HNLF of 2 km length [13] and it was found that DPSK outperforms intensity modulation formats. Therefore, in the proposed SS-WDM-FSO system, another differential phase modulation technique DQPSK, is investigated and a comparison is made with both the investigated DPSK format [13] and the intensity modulation formats [11].…”

A spectrum-sliced (SS) Wavelength division multiplexing (WDM) based Free-space optical (FSO) communication system at a data rate of 2.5 Gbps per optical carrier is proposed in this research article. Utilizing the broadening of the spectrum by means of supercontinuum generation in a highly non linear Fiber (HNLF), an SS-WDM based FSO system is designed. The narrow spectrum of laser light source is broadened by means of self phase modulation (SPM). The proposed work reveals that the DQPSK based SS-WDM FSO system has higher performance compared to intensity modulation formats as well as other differential phase modulation formats. Considering various values of FSO link distances, antenna diameters of transmitter and receiver, beam divergence and thus, determining the values of performance metrics such as Q-factor and bit error rate (BER), differential quadrature phase shift keying (DQPSK) based SS-WDM FSO system is simulated. The same process is repeated for dual channel FSO system for DPSK and DQPSK.

With the motive to reduce the high cost incurred in Wavelength division multiplexing (WDM) based free-space optics (FSO) communication system, Spectrum-sliced (SS) WDM based FSO communication system at a data rate of 2.5 Gbps per channel is proposed in this research article. Utilizing the broadening of the spectrum by means of supercontinuum generation in a highly non linear Fiber (HNLF), an economical SS-WDM based FSO system is designed. The narrow spectrum of laser light source is broadened by means of self phase modulation (SPM). The proposed work confirms that the DQPSK based SS-WDM FSO system has higher performance in terms of Q-factor and BER compared to other intensity modulation formats as well as differential phase modulation formats. Considering various values of FSO link distances, antenna diameters of transmitter and receiver, beam divergence and thus, determining the values of Q-factor and BER, Differential quadrature phase shift keying (DQPSK) based SS-WDM FSO system is simulated.
