High-tolerance grating couplers for vertical backside coupling

HIGHLIGHTS

• What: In Figure 4a, the authors show T2=330 nm, T3=205 nm, T4=354 nm, and Lf=5.6 µm. In Figure 4a, the authors show the 2D the 2D FDTD simulated electric field profile within and around the GC at 1550 nm, when FDTD simulated electric field profile within and around the GC at 1550 nm, when the the grating is illuminated with the fundamental z-polarized fiber mode.
• Who: Jui-Hung Chen and colleagues from the Department of Photonics, National Cheng Kung University, No, University Rd, Tainan City, Taiwan have published the . . .
