“…The short CLs of 482 µm as well as the low crosstalk were the main advantages of the splitter. The RI discrepancy between NLC and silica of the PCF guarantees the index-guiding mechanism [119]. A core-MF-core sandwich structure was designed so as to adapt the application area in magnetic field sensing.…”

Photonic crystal fibers (PCFs) have brought tremendous advancements due to their predominant features of peculiar air-holes arrangement in two-dimentional direction. Functional materials like metals, magnetic fluids, nematic liquid crystals, graphene and so on, are extensively adopted to integrate with PCFs to get extraordinary transmission properties. This review takes the development stages of photonic devices based on functional materials-infiltrated PCFs into consideration, covering the overview of common materials and their photoelectric characteristics, the state-of-art infiltrating/coating techniques, as well as the corresponding applications involving polarization filtering and splittering devices in optical communication and sensing elements related to multiple parameters measurement. The cladding air hole of PCFs provides a natural optofluidic channel for materials being introduced, light-matter interaction being enhanced, and transmission properties being extended, where a lab on a fiber are able to be proceeded. It paves a space for the development of photonic devices in the aspects of compact, multi-functional integration, and electromagnetic resistance as well. According to surface plasmon resonance, the property of tunable refractive indices, and the flexible geometry structures, it comes up to some representative researches on polarization filters, multiplexer-demultiplexers, splitters, couplers and sensors, making a candidate for widespread fields of telecommunication, signal-capacity, and high-performance sensing.

Infrared optical detection devices such as photodetectors, solar cells, cameras, and microbolometers are becoming smaller in size with a tiny active area in the range of a few micrometers or even nanometers. That comes at the expense of a smaller aperture area of the device, and in turn inefficient collection of infrared energy. Therefore, infrared plasmonic optical antennas are becoming essential to efficiently collect optical energy from free space and concentrate it down to the device’s tiny area. However, it is desirable to develop plasmonic antennas with a broad bandwidth, polarization insensitivity, wide field-of-view, and reasonable plasmonic losses. That ensures collection of most incident infrared radiation and enhancement of power absorption efficiency. In this chapter, some types of plasmonic antennas are explored with an emphasis on innovative type of optical antenna called Bundt Optenna. We investigate Bundt Optenna design and optimization. This antenna has a novel shape that looks like a Bundt baking pan and it is made of gold. Several Bundt unit cells can be arranged in a periodic array that is placed on top of a thin-film infrared absorbing layer. The Bundt Optenna utilizes surface plasmons to squeeze both electric and magnetic fields of infrared radiation down to a 50 nm wide area, thus enhancing absorption efficiency within an underneath thin-film layer. The Optenna demonstrates polarization insensitivity and ultra-broad bandwidth with a large fractional bandwidth within the near, short-wave, and mid-wave infrared bands. It also shows a remarkable enhanced power absorption efficiency and a wide field-of-view.
