文摘
- •
Finds the conditions of 3 dB-DC insensitive to the changes of physical parameters.
- •
An asymmetric MZI structure to improve the error tolerance of device performance.
- •
Asymmetric MZI switch verifies the 3 dB-DC error tolerance, then mutually optimize.
- •
The agreements among the numerical, BPM software and experimental results.
- •
10% tolerances of WG width/indices make silica-PLC MZI-switch more applicable.
