“…In addition, the multi-input multi-output (MIMO) technique is used to get more bandwidth and throughput in the FSO system. The optical coding division multiple access (OCDMA) technique is used in FSO system [33]. This scheme has several advantages like flexibility of the channel allocation, asynchronously operative ability, privacy enhancement, and network capacity increment.…”

In this work, we report the use of self-phase modulation in a high nonlinearity fiber for super continuum frequency generation which is spectrum-sliced using a demultiplexer. Four channels (193-193.225 THz) are sliced with 75 GHz channel spacing. Each wavelength channel transports two distinct sub-channels with 20 Gbit/s-40 GHz data rate over different Laguerre Gaussian spatial modes (LG02 and LG03) using the proposed hybrid spectrum sliced-wavelength division multiplexing-mode division multiplexing based orthogonal frequency division multiplexing-radio-over-free space optics link. The performance of the proposed link is investigated using numerical simulations. 160 Gbit/s-320 GHz data is transmitted at 20 km for clear conditions with reliable performance. We have also analyzed the link performance under different level of fog weather. Further to maximize the link reach, we have proposed an enhanced detection at the receiver terminal. The results of numerical investigation of the link show an improvement of 40 dB in signal-to-noise ratio and received power under different weather conditions using the proposed detection technique.

“…Laguerre Gaussian modes have numerous advantages such as they lower the overall cost of the system, competent to support high data rates, and provide less crosstalk among different channels due to different mode profiles. MDM integrated OCDMA had been implemented for the transmission of data over free space channel having distance of 8 km …”

“…MDM integrated OCDMA had been implemented for the transmission of data over free space channel having distance of 8 km. 7 Sixty-four channel WDM IS-OWC system was proposed at the different bit rates using different modulation techniques such as Carrier suppressed RZ, Duobinary RZ, and Modified Duobinary RZ. Carrier Supressed RZ provides best quality factor and wide eye opening than DRZ and MDRZ modulation techniques at 10 Gbps and 20 Gbps.…”

The article presents the comprehensive approach of designing MDM in Inter‐Satellite OWC system using CSRZ‐DQPSK, DRZ‐DQPSK, and MDRZ‐DQPSK modulation system. The 64 Laguerre Gaussian modes are integrated to enhance the system's capability. The proposed system is designed for 64 channels having distances varied from 900 to 4500 km at various data rates. The mode division multiplexing concept is implemented over WDM because it uses single laser source and enhance the capacity of optical networks. Performance of proposed system is examined by comparing the eye diagrams and Q‐factor. It is observed from the outcomes that MDRZ‐DQPSK modulation presents superior Quality factor of 19.42 then DRZ‐DQPSK and CSRZ‐DQPSK Modulation with the favorable distance upto 4500 km at 10 Gbps bit rate. MDRZ‐DQPSK modulation technique performs well till 40 Gbps whereas CSRZ‐DQPSK Modulation exhibits least Q‐factor due to high consumption of bandwidth but it saves cost and preferable for long reach transmission.
