“…Bulk-optic mode converters require critical alignment and have a large insertion loss. To overcome these problems, several fiber mode converters (using mode-selective directional couplers [1][2][3]21] and long-period gratings (LPGs) [22][23][24]) and waveguide mode converters (using Y-junctions [25], Mach-Zehnder interferometers [26,27], LPGs [18,19], etc.) have been proposed.…”

Mode division multiplexing (MDM) is currently one of the most attractive multiplexing techniques in optical communications, as it allows for an increase in the number of channels available for data transmission. Optical modal converters are one of the main devices used in this technique. Therefore, the characterization and improvement of these devices are of great current interest. In this work, we present a dataset of 49,736 near-field intensity images of a modal converter based on a long-period fiber grating (LPFG) written on a few-mode fiber (FMF). This characterization was performed experimentally at various wavelengths, polarizations, and temperature conditions when the device converted from LP01 mode to LP11 mode. The results show that the modal converter can be tuned by adjusting these parameters, and that its operation is optimal under specific circumstances which have a great impact on its performance. Additionally, the potential application of the database is validated in this work. A modal decomposition technique based on the particle swarm algorithm (PSO) was employed as a tool for determining the most effective combinations of modal weights and relative phases from the spatial distributions collected in the dataset. The proposed dataset can open up new opportunities for researchers working on image segmentation, detection, and classification problems related to MDM technology. In addition, we implement novel artificial intelligence techniques that can help in finding the optimal operating conditions for this type of device.

“…Another experiment [28] reported zero dispersion PCF (with low confinement loss) to minimize dispersion in sensor and optical fiber communication systems. An experiment in 2016 [29] used a dual-core PCF-based mode selective coupler for mode conversion between LP 01 and 11 modes. Another experiment in 2017 [30] used dual-core PCF with magnetic fluids in an air hole to polarize beam splitters.…”

Radio over free space (Ro-FSO) provides an ambitious platform for seamless integration of radio networks to optical networks. Three independent channels, each carrying 2.5 Gbps-5 GHz data, are successfully transmitted over a free space link of 2.5 km by using mode division multiplexing (MDM) of three modes LG 00, LG 01, and LG 02 modes in conjunction with solid core photonic crystal fibers (SC-PCFs). Moreover, SC-PCFs are used as a mode selector in the proposed MDM-Ro-FSO system. The results are reported in terms of bit error rate, mode spectrum, and spatial profiles. The performance of the proposed Ro-FSO system is also evaluated under the influence of atmospheric turbulence in the form of different levels of fog, namely, light fog, thin fog, and heavy fog.

“…In 2016 [9], the authors demonstrated a dual-core PCF for mode conversion (between LP 01 and LP 11 modes; and LP 01 and LP 21 modes). Authors from another work [10] showed a mode selective coupler based on a dual-core PCF for mode conversion between LP 01 and LP 11 modes.…”

This work is focused on the transmission of linearly polarized (LP) 01 and LP 02 modes over a solid-core photonic crystal fibre (PCF) with the length of 100 µm. The performance of LP 01 and LP 02 modes is evaluated in terms of relative powers and spatial profiles. Moreover, optimization of the wavelengths and the spacing size between the air holes (pitch) is carried out. The main contribution of this work is to design a solid-core PCF for the transmission of LP 01 and LP 02 modes through it. The proposed PCF can be used for spatial division multiplexing as well as for short-haul communication purposes.
