Mode resolved bend loss in few-mode optical fibers
Optics Express, 2013 We present a novel approach to directly measure the bend loss of individual modes in few-mode fibers based on the correlation filter technique. This technique benefits from a computer-generated hologram performing a modal decomposition, yielding the optical power of all propagating modes in the bent fiber.

The monitoring system for the aerogel Cherenkov counter of the BELLE detector [PDF]
, 1998 We report on a design and performances of a monitoring system developed for the aerogel Cherenkov counters (ACC) of the BELLE detector. The system consists of blue LEDs, a diffuser box, and optical distributors which distribute the LED light to the ACC ...

Birefringence and polarisation mode-dispersion in spun single-mode fibres
, 1981 A theoretical and experimental analysis of the polarization properties of twisted single-mode fibers is presented. It is shown that whereas a conventionally twisted fiber possesses considerable optical rotation, a fiber which has a permanent twist ...

Mode Multiplexing and High Efficient Switching in Few-Mode Fiber Based on Modeled Blazed Grating
IEEE Photonics Journal, 2016 We propose a novel approach based on modeled blazed grating (MBG) to realize the mode conversion, multiplexing, demultiplexing, and switching in few-mode transmission fibers.
