Separate search groups with parentheses and Booleans. An optical amplifier in the 1.3-μm window is also analyzed. 16(3) 174-176 (1991), David H. Leach, Richard K. Chang, and William P. Acker This paper describes the experimental investigation of stimulated Raman scattering obtained from a multimode fiber. The weaker (low frequency) spectral component is amplified and the gain is G=99-61.7=37.3 dB.

With 30 m of the fiber, the scattered waves (the Stokes waves) in the fiber could be made to propagate predominantly in one of the low-order modes of the fiber by careful adjustment of the light-launching conditions.

Stimulated Raman scattering in a 50-μm multimode graded-index optical fiber was studied with a pulsed dye laser as the pump source. Electr. Figure 4 gives the output spectrum. Lett. We present a numerical method that involves the simultaneous solution of integral equations describing SRS in optical fiber. Get access to all our software tools instantly!

Keep it simple - don't use too many different parameters. We use cookies to improve your website experience. This lesson demonstrates the light amplification caused by the stimulated Raman scattering effect. Registered in England & Wales No. The method is general enough to be applicable for wavelength division multiplexing (WDM), optic frequency division multiplexing (OFDM), and optical amplification. You may subscribe either as an OSA member, or as an authorized user of your institution. You do not have subscription access to this journal. The effect of stimulated Raman scattering (SRS) in fiber optic communications is considered.On one hand, SRS limits the launch power in a multiple-channel communication system; while on the other hand, SRS can provide optical amplification in the 1.3-μm and 1.55-μm windows. The system parameters are such that the other nonlinear effects, such as stimulated Brillouin scattering and four-wave mixing, are less significant for the system. TD 5 : Raman Scattering in an optical fiber The stimulated Raman scattering (SRS) corresponds to the conversion of a laser beam at ν P to a beam whose frequency is shifted to ν S = ν P – Ω (Stokes wave).

With 30 m of the fiber, the scattered waves (the Stokes waves) in the fiber could be made to propagate predominantly in one of the low-order modes of the fiber by careful adjustment of the light-launching conditions. 3099067 3 refs., 2 figs. The effect of stimulated Raman scattering (SRS) in fiber optic communications is considered. 5, 1 (1977). We've also updated our Privacy Notice. However, it is efficient and simple to program and uses just a few realistic assumptions. Cited by links are available to subscribers only. A solution is usually obtained by solving differential equations. Ω is associated to a vibrational transition in the non-linear medium. Stimulated Raman scattering in a 50-μm multimode graded-index optical fiber was studied with a pulsed dye laser as the pump source. Login to access OSA Member Subscription. A. Sharma, M.

Contact your librarian or system administrator The receiver dynamic range over the wavelengths of interest is an important factor in determining the launch power limitations. We show that the response-function based computational approach to Raman scattering predicts accurately many of the propagation properties of picosecond pulses in single-mode optical fibers.
