Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings
Light: Science & Applications, 2015 Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods. Orbital angular momentum (OAM) in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of ...

Direct characterization of the spatial effective refractive index profile in Bragg gratings
, 2005 We propose a pulse response method to directly characterize the phase of the spatial index modulation, including the dc refractive index distribution (distributed phase shift), discrete phase, and chirp of fiber Bragg gratings (FBGs).

Thermal dependence of the strain response of optical fibre Bragg gratings. [PDF]
, 2004 The temperature dependence of the strain sensitivity of fibre Bragg gratings written into a number of different fibre types has been investigated. It was found that the strain response changed on average by 0.21 ± 0.03 fm µε-1 °C-1 over a range of ...

Fabrication of rGO-GO Long Period Fiber Grating Using Laser Reduction Method
IEEE Photonics Journal, 2017 A laser-reduction technique is investigated to fabricate a novel long period fiber grating (LPFG), whose period is a section of graphene oxide (GO) and reduced graphene oxide (rGO) films on a side polished fiber.
