We demonstrated both theoretically and experimentally robust single-mode operation in all-solid photonic bandgap fibers with record effective mode areas of ∼2650μm2 by introducing multiple strongly coupled smaller cores in the cladding.
Photonic bandgap fibers (PBF) offer many unique properties and are critical to many emerging applications, some requiring very wide bandgaps. We will demonstrate theoretically and experimentally PBFs with square lattice can provide much wider bandgaps.
This paper presents the development of three-fluid coaxial electrospinning technology and its application in electroluminescent organic light emitting micro/nanofibers (OLEFs). It is demonstrated that one-dimensional micro/nano-scale light sources can be realized using a single-step, substrate-free fabrication process - three-fluid coaxial electrospinning. The OLEF devices are formed in air rather...
The paper report a novel optical diffraction chemical and biological sensor using stimuli-responsive hydrogel grating fabricated through ultraviolet (UV)-assisted micro-imprinting technology. Hydrogel grating swells and shrinks upon exposure to the analyte of interest, thus causing to change the periodicity of the grating. This results in a change in diffraction pattern (i.e., size, brightness, and/or...
