Understanding the Phase Shift Formula in Stimulated Brillouin Scattering

Click For Summary
SUMMARY

The discussion centers on the phase shift formula in stimulated Brillouin scattering (SBS), specifically regarding the role of the imaginary part of the complex gain. Participants highlight that the phase shift is influenced by a coefficient beyond the gain coefficient (go), which is defined as power over effective area. Additionally, the effective length's relationship with this constant is questioned, emphasizing the need for clarity on how these factors interact in the context of phase shifters.

PREREQUISITES
  • Understanding of stimulated Brillouin scattering (SBS)
  • Familiarity with complex gain in optical systems
  • Knowledge of phase shift calculations in wave propagation
  • Basic principles of optical fiber communication
NEXT STEPS
  • Research the derivation of the phase shift formula in stimulated Brillouin scattering
  • Study the role of the imaginary part of complex gain in optical systems
  • Explore the relationship between effective length and phase shift in SBS
  • Examine textbooks on optical fiber communication for detailed explanations of phase shifters
USEFUL FOR

Researchers, optical engineers, and students studying photonics or fiber optics who seek a deeper understanding of phase shifts in stimulated Brillouin scattering.

Good morning
I need to ask about the exact formula for the phase shift used in stimulated Brillouin scattering especially in the phase shifter thank you
 
Science news on Phys.org
What have you already found? This is a pretty broad topic.

What I know is usually the imaginary part of the complex gain but I really want to know that there is a coefficient other than go which is power over effective area
I need to know if also the effective length is also multiplied to this constant
 
Which books are you using?
 
What I know from any book that you derive from the complex gain the real and imaginary part
The imaginary part is related to the phase but I need to know what factors multipled to this imaginary part??
