Intermediate mode interchange using low-crosstalk mode multiplexer/demultiplexer in a 6 mode-division multiplexed transmission line has been demonstrated. We experimentally confirmed the reduction of differential mode group delay and tap size in 12×12 MIMO equalizer.

New multi-mode delay differential equation model for lasers with optical feedback
Optical and Quantum Electronics, 2016In this paper, we discuss the relations between the spatially-distributed traveling wave, Lang-Kobayashi, and a new multi-mode delay differential equation models for Fabry-Perot type semiconductor diode lasers with an external optical feedback. All these models govern the dynamics of the slowly varying complex amplitudes of the optical fields and ...

Sliding mode control for a class of stochastic partial differential system with time-delay
ICARCV 2004 8th Control, Automation, Robotics and Vision Conference, 2004., 2005Sliding mode control problem for a class of stochastic partial differential system with time-delay are studied. Variable structure controllers are designed for the system. The existence of sliding mode motion is shown. And the stability character is analyzed.

Optics Letters, 2000
We study the frequency autocorrelation of the differential group delay (DGD) in fibers with polarization mode dispersion (PMD). We show that the correlation bandwidth of the DGD is comparable with that of the orientation of the PMD vector. Furthermore, we show that all the most general statistical properties of polarization mode dispersion in long ...

Differential Mode Delay Measurements of Fluorinated Graded Index Polymer Optical Fiber
IEEE Photonics Technology Letters, 2008We have performed a detailed study of four different perfluorinated graded index polymer optical fibers issued from two manufacturers. After the description of the test bench that has been set up in order to measure the differential mode delays, we report on the corresponding measurements in time domain and the deduced ones in the frequency domain ...

Measuring distributed mode scattering in few mode fibers with high and low differential group delay
2012 IEEE Photonics Society Summer Topical Meeting Series, 2012We present measurements of distributed mode scattering in up to 30km long few mode fibers using spatially and spectrally resolved (S2) imaging.

Differential Delay of Ordinary and Extraordinary Modes of Transionospheric Radio Waves
Journal of Geophysical Research: Space PhysicsAbstractThe terrestrial ionosphere is a birefringent medium that allows radio waves to propagate in two modes: the ordinary (O‐mode) and the extraordinary (X‐mode). A difference in the index of refraction of the two modes results in differential delay (mode delay) between the O‐ and X‐modes of radio waves propagating through the ionosphere. Mode delays
