Fiber-diffraction Interferometer using Coherent Fiber Optic Taper [PDF]
, 2010 We present a fiber-diffraction interferometer using a coherent fiber optic taper for optical testing in an uncontrolled environment. We use a coherent fiber optic taper and a single-mode fiber having thermally-expanded core.

Operating penalties in single-fiber operation 10-Gb/s, 1024-way split, 110-km long-reach optical access networks [PDF]
, 2006 We report for the first time optical signal-to-noise penalties which lead to performance degradations in single-fiber long-reach optical access networks when compared to identical dual-fiber systems.

Generation of the First-Order OAM Modes in Ring Fibers by Exerting Pressure Technology
IEEE Photonics Journal, 2017 We have proposed an effective method of generating the first-order orbital angular momentum (OAM) modes in ring fibers. The first-order OAM modes (${\rm{L = \pm 1}}$ ) can be represented as the linear superposition of the ${\rm{HE}}_{{21}}^{{\rm{even}}}$

Nanomechanical optical fiber [PDF]
Optics Express, 2012 Optical fibers are an excellent transmission medium for light and underpin the infrastructure of the Internet, but generally after fabrication their optical properties cannot be easily modified. Here, we explore the concept of nanomechanical optical fibers where, in addition to the fiber transmission capability, the internal core structure of the fiber
