Cladding-mode resonances in hybrid polymer-silica microstructured optical fiber gratings

Highly nonlinear photonic crystal fiber with ultrahigh birefringence using a nano-scale slot core

“…Thus, a PCF with two rectangular air-holes in the core region should be able to be fabricated. After doing that, we can use the high pressure chemical vapor deposition method to deposit silicon in the rectangular air-hole [31], or use the fiber post-processing technique to fill the rectangular air-hole with silicon strip [32], and then, the proposed PCF should be fabricated.…”

Gaussian Filtering with Tapered Liquid Crystal Photonic Bandgap Fibers

“…Optical properties of these fibers may be manipulated by filling the air holes with liquid materials. In [3,4] a device with tunable transmission properties was demonstrated by filling the air holes with polymers and with a high-index liquid, respectively. In [5] for the first time, it was shown that Liquid Crystal (LC) filled PCFs may form tunable photonic bandgap waveguides.…”

Programmable long-period grating in a liquid core optical fiber

“…Although silica fibers are an excellent platform for low loss waveguiding, they are somewhat limited in terms of their functionality owing to their low linear, nonlinear and thermal optical coefficients, for example. Therefore, in order to introduce some reconfigurable behavior into these fibers they are often infiltrated with materials that have tunable optical properties such as polymers [1], liquids [2], liquid crystals [3] and gases [4]. Of these hybrid-material structures liquid-filled optical fibers have been the most widely investigated owing to the relative ease of fabrication, but also because there is a long list of liquids that offer many useful properties for photonics applications including low loss, broadband transmission windows [5].…”
