WebJun 12, 2024 · In this work, a bidirectional grating coupler for perfectly vertical coupling is proposed. The coupling efficiency is enhanced using a silicon nitride (Si3N4) layer above a uniform grating. In the presence of Si3N4 layer, the back-reflected optical power into the fiber is diminished and coupling into the waveguide is increased. Genetic algorithm (GA) … WebApr 12, 2024 · In the control system, κ l = κ r ≪ 1,there is no coupling between CW and CCW mode, so the reflection Rl and Rr are always 0. The transmission of the two ports is Tl = Tr = ∣ sl − √2γ2acw ∣ 2 s2 l = ( ω − ω0) 2 + ( γ0 + γ1 − γ2) 2 ( ω − ω0) 2 + ( γ0 + γ1 + γ2) 2, which shows a Lorentzian profile.
