Рассмотрены основные тенденции развития современных магистральных оптических систем дальней связи. Это прежде всего усложнение форматов модуляции сигнала, увеличение символьной скорости в оптическом тракте, применение суперканалов и формирование спектра сигнала, управление спектром (FlexGrid), развитие усилителей в новых спектральных диапазонах, исследование маломодовых и многосердцевинных оптических волокон. Показано, что существующие технологии теоретически позволяют достичь пропускной способности порядка 100 Тбит/с по одному волокну. Для дальнейшего увеличения пропускной способности требуются использование новых спектральных диапазонов или пространственное мультиплексирование с применением новых типов оптических волокон. Ключевые слова: DWDM, волоконно-оптическая сеть связи, когерентный прием, спектральная эффективность, формат модуляции, символьная скорость, формирование спектра, управление спектром, FlexGrid, NyquistWDM, суперканал, маломодовые волокна, многосердцевинные волокна.

“…[23,24] In optoelectronics, a dielectric material with a very low refractive index is a key component of the optical parts. [25,26] Important optical applications include anti-reflective coatings, optical lens coatings, optical adhesives, fiber optic core and cladding, and encapsulation of various optical components. [25,27] Nanoporous films are well known for exhibiting very low refractive indices.…”

Photonic crystals (PC) are of great importance in technology, especially in optics and photonics. In general, the structural color of PCs responds to external stimuli primarily by changing their periodicity. Herein, the authors report on refractive index (RI) adaptive PCs. Cross‐linked cholesteric films with interconnected nanopores exhibit a very low RI without light scattering. Transparent PC films with maximum reflectance in the ultravoilet (UV) region respond to various chemicals by changing the reflective color of the PC. The authors demonstrate its unique colorimetric chemical detections of hazardous organic liquids. Loading various chemicals into nanopores significantly shifts the structural color into the visible range depending on the chemical's RI. These results are unique in that the structural color of photonic films is mediated by RI changes rather than periodicity changes. In principle, nanoporous photonic crystal films can detect the RI of a chemical substance by its unique color. In contrast to volumetric changes, this sensing mechanism offers several advantages, including durability, excellent sensitivity, fast response time, and wide detection range. These results provide useful insight into stimulus‐responsive PCs. The structural color of PC films can be effectively tuned by adjusting average RIs instead of changing periodicity.

“…This requires the use of materials, for example Si 3 N 4 [14,15], Ti 2 O [16], Al 2 O 3 [17], among others, that allow the realization of devices of smaller waveguides, which operate in a wider spectral range e.g. 200 nm to 2000 nm [18][19][20].…”

Optical coupling gratings are strategic components of integrated optics that allow the interaction of a laser signal with optical interconnects, integrated photonic microdevices and biosensors. In this work, the design of binary and sinusoidal type coupling gratings for Al2O3/SiO2/Si submicron guides operating in the visible (633 nm) and infrared (1550 nm) is presented herein. In particular, the coupling efficiency is analyzed as a function of the main design parameters: waveguide thickness, period, etch depth and incidence angle. The results indicate that coupling efficiencies of 21 and 15 percent and decoupling efficiencies of 25 and 22 percent can be obtained for binary and sinusoidal gratings, respectively, at a wavelength of 1550 nm; coupling efficiencies of 7.8 and 7.6 percent and decoupling efficiencies of 53 and 34 percent can be obtained for a wavelength of 633 nm. The proposed designs have potential applications for the fabrication of integrated circuits.
