WebOct 3, 2012 · The optical modulation is produced by the deliberate change of the real part Δ n′ of the optical index, through the electro-optic effect, or of the imaginary part Δ n″ through laser gain or absorption control. The general expression for the refractive index n ( t) of the driven modulating device is in the form: (3.36) WebA low-cost and high-efficiency scheme of optical labels enabled optical performance monitoring using m-sequence spread spectrum is proposed. The information of optical labels can be demodulated without errors at low system OSNR penalty in C …
