摘要
Complete mean refractive index compensation should include apodization and sampling compensation. However, numerical simulations show that only apodization compensating is required. A simple compensation technique is proposed and demonstrated. Receding the fiber outside the coherent zone, apodization compensation is implemented by controlling the exposure position and exposing time of argon ion laser. The side lobes of reflection spectrum is suppressed. Group delay ripple is smoothed.
