Polarization-Induced Fading in Fiber-optic Sensor Arravs
The statistics of polarization-induced visibility fading is studied for fiber-optic interferometric (Michelson or Mach-Zehnder) sensor arrays made of either regular singlemode fibers or polarization-maintaining fibers. Performance is measured in terms of the probability to observe visibilities, all of which exceed a given value, for all members of the array. Very poor performance is obtained fo...
متن کاملA Novel Differential Polarization-shift Keying Scheme for Fiber-optic Communication System
The rapid development of fiber-optic communication system requires a increasing transmission data rate and reach. One of the challenge for long-haul high-speed fiber-optic system is how to reduce the impairments and degrading effects from fiber dispersions and nonlinearity. Although the advances of digital signal processor (DSP) make impairment compensation for the coherent systems become possi...
متن کاملStudy on Polarization Effects Based on Fiber-Optic Vibration Sensor
An analysis based on the Jones matrix theoretical analysis is presented in this paper, which is based on the distributed optical fiber vibration sensor to study the polarization effect. A new improved distributed optical fiber structured is designed by using a Faraday rotation mirror ,the system remove the linear birefringence and the orientation birefringence, and it is insensitive to the chan...
متن کاملPolarization-coupling all-fiber acousto-optic tunable filter insensitive to fiber bend and physical contact.
We show that an all-fiber acousto-optic tunable filter based on polarization mode coupling using torsional acoustic wave is immune to the fiber bend and physical contact in the acousto-optic interaction region. We also propose and demonstrate a novel strain-free and size-reduced tunable filter with a 4-m-long fiber acousto-optic interaction region looped into a 5- cm-diameter coil.
متن کاملA Transflective Nano-Wire Grid Polarizer Based Fiber-Optic Sensor
A transflective nano-wire grid polarizer is fabricated on a single mode fiber tip by focused ion beam machining. In contrast to conventional absorptive in-line polarizers, the wire grids reflect TE-mode, while transmitting TM-mode light so that no light power is discarded. A reflection contrast of 13.7 dB and a transmission contrast of 4.9 dB are achieved in the 1,550 nm telecom band using a 20...
