Lossless, Non-Volatile Post-Fabrication Trimming of PICs via On-Chip High-Temperature Annealing of Undercut Waveguides
Yating Wu, Haozhe Sun, Bo Xiong +5
Limited by equipment precision, manufacturing deviations in waveguide width, etch depth, and layer thickness inevitably occur in photonic integrated circuits (PICs). These variatio…

Ultralow-Crosstalk Silicon Electro-Optic Switch with Cascaded Phase Shifters for Loss Equivalence
Yating Wu, Tao Chu
In silicon electro-optic (EO) Mach-Zehnder interferometer (MZI) switches, crosstalk is typically limited by beam imbalance between the MZI arms, primarily caused by the free carrie…

A general designing approach for polarization-independent photonic on-chip systems
Yating Wu, Xiaoyan Liu, Tao Chu
Due to that the polarization states in optical fibers change randomly during transmission, polarization-independent (PID) devices are demanded to receive lights with arbitrary pola…
