All-optical broadcast technology based on aluminum-doped highly nonlinear fiber

Abstract

Abstract. Making use of the four-wave mixing, a realization of all-optical 1 × 6 broadcast technology based on aluminum-doped highly nonlinear fiber (AL-HNLF) is performed. In the system, a set of experiments at channel intervals of 50, 100, and 200 GHz are conducted, and clear eye diagrams as well as low error performance are obtained with an input optical signal of a continuous wave and a 10-Gb∕s return-to-zero on-off keying signal, which mostly benefits from the AL-HNLF used in this system. In detail, resulting from the high stimulated Brillouin scattering threshold of AL-HNLF, more power can be launched into the fiber. Additionally, similar performances of different channel spaces demonstrate the adjustability for this technology. With these distinguishing features, this technology might satisfy the basic expectation of utility.

Far-zone behaviors of scattering-induced statistical properties of partially polarized spatially and spectrally partially coherent electromagnetic pulsed beam*

“…Other values could also be used depending on the situations. Moreover, all of the parameters satisfy the following beam conditions [22]…”

“…describing the spectral width and the spectral coherent width of the pulse, respectively. [22] Based on the CSD matrix of an electromagnetic pulsed beam, there are three important fundamental statistical properties of the incident field that could be defined as the average spectral intensity, [23] S 0 (𝜌, ω) = Tr 𝑊 (0) (𝜌, 𝜌, ω, ω)…”

“…[2,3,18,19] A typical non-stationary stochastic source called spatially and spectrally partially coherent pulses was introduced by Lajunen et al [20] By extending the notion of the CSD matrix from stochastic electromagnetic stationary beams to stochastic electromagnetic pulsed beams, we explored the propagation properties of a partially polarized spatially and spectrally partially coherent electromagnetic Gaussian Schell-model pulsed (EGSMP) beam in a turbulent atmosphere. [21][22][23] To the best of our knowledge, an investigation of the statistics of a partially polarized spatially and spectrally partially coherent electromagnetic pulse irradiating on a deterministic scattering medium has not been presented thus far. For this reason, based on the theory of the first-order Born approximation, we explore the case of a partially polarized spatially and spectrally partially coherent EGSMP beam interacting with a deterministic scattering medium.…”
