Suppression of Rayleigh Backscattering in Resonators
2018 IEEE Photonics Conference (IPC), 2018We demonstrate dynamic suppression of Rayleigh backscattering in a whispering gallery mode resonator by locally breaking time-reversal symmetry through a Brillouin optomechanical interaction.

Rayleigh Backscattering in Few-Mode Optical Fibers
Optical Fiber Communication Conference, 2016We measure inter-modal Rayleigh backscattering in few-mode optical fibers and compare the experimental results with simulation results obtained from newly-developed analytical formulae. Excellent agreement between theory and experiment allows investigation of mode-coupling dynamics using OTDR.

Non-Rayleigh statistics of ultrasonic backscattered signals
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1994The statistics of the envelope of the backscattered signal from tissues have been known to vary from the well-known Rayleigh model. The K-distribution is used to model this non-Rayleigh behavior, since the generalized K-distribution encompasses a wide range of distributions like Rayleigh, Lognormal, and Rician. Computer simulations were conducted using

Temperature retrievals by Rayleigh backscatter lidar signals
Applied Optics, 1986Differences between retrieved temperatures from lidar and atmospheric model temperatures are calculated for four problems: (1) the effect of a transient thin aerosol layer at any altitude on temperature retrieved by a single-wavelength lidar; (2) the effect of residual aerosols on temperature retrieved by a two-wavelength lidar; (3) the errors due to ...

RSOA as a sawtooth generator for Rayleigh Backscattering effect mitigation
36th European Conference and Exhibition on Optical Communication, 2010Sawtooth signal at 2.5GHz has been obtained with an RSOA of 1GHz bandwidth. A measured wavelength shifting of 2.5GHz, obtained with the RSOA chirp induced phase modulation, allows 5dB Rayleigh Backscattering effect mitigation.

Rayleigh backscattering in optical fiber recirculating delay lines
Applied Optics, 1986We derive the backscattering impulse response of a recirculating fiber delay line. The response consists of periodic discontinuities that occur at multiples of the loop transit time. The magnitude of each discontinuity is found to depend only on the coupling coefficient and the number of recirculations and is independent of both propagation loss and ...

Interferometry with Rayleigh backscattering in a single-mode optical fiber
Optics Letters, 1994A novel distributed sensing technique based on reflectometry is proposed. The technique uses the interference of the light waves backscattered within the resolution range of a reflectometer to detect the optical path changes in a single-mode fiber. Experimental results are presented, and practical realization of an intrusion detector that employs this ...

Rayleigh Backscattering Signatures of Optical Fibers—Their Properties and Applications
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013The properties of optical fiber Rayleigh scatter are reviewed from the perspective of high resolution, high sensitivity OFDR measurements. The statistical properties of single mode fiber are reviewed as well as Rayleigh scatter properties of PM fiber and erbium-doped fiber-optic amplifiers.

Backscattering at Rayleigh and other angles: A theoretical prediction
The Journal of the Acoustical Society of America, 1983The spectral representation approach used to calculate beam profile changes upon forward reflection T. D. K. Ngoc and W. G. Mayer, IEEE Trans. Sonics Ultrason. SU-27, 229 (1980)] is extended to include negative angles of reflection, i.e., backscattering. Calculations show that the amplitude of the backscattered beam is a strong function of the incident
