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. WebNov 24, 2024 · The coupling loss between inverse taper and optical fiber mainly comes from three parts, which are the mode mismatching loss between the waveguide and optical fiber, the mode conversion loss in inverse taper and the propagation loss caused by the surface roughness of the waveguide.
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) …
