Block Copolymers as Photonic Bandgap Materials
Block copolymers self-assemble into one-, two-, and three-dimensional periodic equilibrium structures, which can exhibit photonic bandgaps. This paper outlines a methodology for producing photonic crystals at optical length scales from block copolymers. Techniques for enhancing the intrinsic dielectric contrast between the block copolymer domains, as well as increasing the characteristic microd...
متن کاملLow-loss all-solid photonic bandgap fiber.
We report the fabrication and characterization of a new type all-solid photonic bandgap fiber. By introducing an index depressed layer around the high-index rod in the unit cell of photonic crystal cladding, transmission loss as low as 2 dB/km within the first bandgap is realized for the all-solid photonic bandgap fiber with a bandwidth of over 700 nm. The bend loss experiment shows that the ph...
متن کاملThree-dimensional photonic bandgap materials: semiconductors for light*
Photonics, the technology of photons (by analogy to electronics, the technology of electrons) will be the driving force for the advancement of areas such as communications and computing, information technology and probably others such as sensing. Photonic band gap (PBG) materials may answer many of their demands. Trying to understand the physics involved is a challenge very eagerly taken on by ...
متن کاملPhotonic Bandgap Propagation in All-Solid Chalcogenide Microstructured Optical Fibers
An original way to obtain fibers with special chromatic dispersion and single-mode behavior is to consider microstructured optical fibers (MOFs). These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. In this study, the first all-solid all-chalcogenide MOFs exhibiting photonic bandgap transmission have been achieved and ...
متن کاملSolid-core photonic bandgap fibers for cladding-pumped Raman amplification.
Cladding-pumped solid-core photonic bandgap Raman fiber amplifiers are analyzed theoretically as possible candidates for power scaling. An example fiber design with a mode field diameter of 46 µm and a cladding diameter of 250 µm is calculated to exhibit 0.12 dB/km of confinement loss at the first Stokes wavelength and >10 dB/m at the second Stokes wavelength for a pump wavelength of 1.567 µm w...
