“…These methods leverage the wavelength’s invariance during signal transmission, earning them the designation of wavelength-division multiplexing (WDM) methods. Due to their good selection of wavelength, non-polarization sensitivity, and possibility of integrating multiple functions, micro-DOEs are widely employed as multiplexers in the WDM methods [315] . When employing a multilevel DOE for multiplexing, achieving wavelength multiplexing becomes straightforward [316] .…”

Diffractive optical elements (DOEs) are intricately designed devices with the purpose of manipulating light fields by precisely modifying their wavefronts. The concept of DOEs has its origins dating back to 1948 when D. Gabor first introduced holography. Subsequently, researchers introduced binary optical elements (BOEs), including computer-generated holograms (CGHs), as a distinct category within the realm of DOEs. This was the first revolution in optical devices. The next major breakthrough in light field manipulation occurred during the early 21st century, marked by the advent of metamaterials and metasurfaces. Metasurfaces are particularly appealing due to their ultra-thin, ultra-compact properties and their capacity to exert precise control over virtually every aspect of light fields, including amplitude, phase, polarization, wavelength/frequency, angular momentum, etc. The advancement of light field manipulation with micro/nano-structures has also enabled various applications in fields such as information acquisition, transmission, storage, processing, and display. In this review, we cover the fundamental science, cuttingedge technologies, and wide-ranging applications associated with micro/nano-scale optical devices for regulating light fields. We also delve into the prevailing challenges in the pursuit of developing viable technology for real-world applications. Furthermore, we offer insights into potential future research trends and directions within the realm of light field manipulation.

“…This system has been successfully proved using several approaches to mode conversion, including diffractive optical elements, mechanical actuators, integrated photonics, and spatial modulators [4, 7, 10, 16, 22 -25, 28 -32]. The modal converter is a key component in MDM and could be understood in a similar way as the Arrayed Waveguide Gratings (AWG) in Wavelength Division Multiplexing (WDM) [19,24]. With a sight in reconfigu-rable optical networks, between the several techniques that have been applied for mode conversion [5, 22 -24, 28, 31, 33 -42] Spatial Light Modulators (SLM) can perform arbitrary mode conversion, switching and commuting, precisely and dynamically in a controlled way [5, 28, 30, 31, 33 -44].…”

Linearly polarized modes were generated from the fundamental LP01 using Lee holograms displayed on a digital micromirror device. The phase in the holograms was optimized using simulated annealing algorithm and complex amplitude correlation to improve the quality of the converted modes. The correlation measurements, and comparisons between numerical and experimental results, show the fidelity of the obtained modes and the effectiveness of the optimization. Furthermore, the optimized holograms can be combined to generate multiple modes spatially addressed with individual control. The results, and the use of a digital micromirror device instead of the most common liquid crystal modulators, make this method suitable for Modal Division Multiplexing systems and compatible with other optical telecommunication techniques like Wavelength and Polarization Division multiplexing, and reconfigurable optical networks.

“…This collaboration has allowed access to the upscale optical equipment, which did not yet exist in Russia. During two month trips to Jena in the framework of the Russian-German project DLR new important experimental results were obtained by Karpeev, which became the basis of joint works [9][10][11][12]18]. The work [4] laid the physical foundations of development of innovative fiber optic sensors in the future [20][21][22], based on the principles of the mode selection.…”

“…The paper [5] was one of the first dedicated to practical implementation of Modans. The developed technologies made it possible to move to the actual use of Modans for excitation modes in lightguides (optical fibers) to transmit information [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. An important role was played by Karpeev`s cooperation with German scientists from Jena, which began in the GDR, continuing already in the Federal Republic of Germany.…”
