“…for muxing and demuxing, which are inherently lossy. Recent demonstrations of theoretically lossless OAM muxing devices, based on waveguides [55] or freespace optics [18], indicate that the required component technology is concurrently developing to enable realistic deployments of scalable networks based on OAM-MDM. specially designed, and ultimately, it offered only an alternative to commercially available free-space components.…”

Optical vortex beams, possessing spatial polarization or phase singularities, have intriguing properties such as the ability to yield super-resolved spots under focussing, and the ability to carry orbital angular momentum that can impart torque to objects. In this review, we discuss the means by which optical fibers, hitherto considered unsuitable for stably supporting optical vortices, may be used to generate and propagate such exotic beams. We discuss the multitude of applications in which a new class of fibers that stably supports vortices may be used, and review recent experiments and demonstration conducted with such fibers.

“…Hence, by adopting OFDM in FSO, long haul transmissions with higher data rate may be achieved [24][25][26][27][28]. Mode division multiplexing is a more recent development in FSO systems [29][30][31][32]. In an experiment, transmission of 4 × 42.8 Gbps is reported by employing MDM scheme over FSO [33].…”

Abstract:Complementing wireless radio networks with free-space optics (FSO) achieves high data rates by modulating radio subcarriers over an optical carrier without expensive optical fiber cabling, enabling a pervasive platform for reaching underserved areas. In this paper, we review the main features of FSO for terrestrial and inter-satellite communications. Simulations of 1 Gbps data transmission through FSO links in both terrestrial and inter-satellite communications have been investigated to highlight potential atmospheric challenges in FSO.

“…Direct generation of OAM-beams has been demonstrated using a single-mode 860 nm vertical-cavity surface-emitting laser (VCSEL) with the dielectric SPP deposited on its top mirror [27]. A CMOS-compatible photonic integrated circuit (PIC) OAM-(de)multiplexer have been proposed in [28], and in [29] data transmission using the proposed PIC was experimentally demonstrated for two multiplexed OAM states.…”

Abstract:In this paper, we experimentally demonstrate simultaneous wavelength and orbital angular momentum (OAM) multiplexing/demultiplexing of 10 Gbit/s data streams using a new on-chip micro-component -tunable MEMS-based Fabry-Perot filter integrated with a spiral phase plate. In the experiment, two wavelengths, each of them carrying two channels with zero and nonzero OAMs, form four independent information channels. In case of spacing between wavelength channels of 0.8 nm and intensity modulation, power penalties relative to the transmission of one channel do not exceed 1.45, 0.79 and 0.46 dB at the harddecision forward-error correction (HD-FEC) bit-error-rate (BER) limit 3.8 × 10 -3 when multiplexing a Gaussian beam and OAM beams of azimuthal orders 1, 2 and 3 respectively. In case of phase modulation, power penalties do not exceed 1.77, 0.54 and 0.79 dB respectively. At the 0.4 nm wavelength grid, maximum power penalties at the HD-FEC BER threshold relative to the 0.8 nm wavelength spacing read 0.83, 0.84 and 1.15 dB when multiplexing a Gaussian beam and OAM beams of 1st, 2nd and 3rd orders respectively. The novelty and impact of the proposed filter design is in providing practical, integrable, cheap, and reliable transformation of OAM states simultaneously with the selection of a particular wavelength in wavelength division multiplexing (WDM). The proposed on-chip device can be useful in future high-capacity optical communications with spatial-and wavelengthdivision multiplexing, especially for short-range communication links and optical interconnects.
