Abstract: We demonstrate an ultra-compact 50-Gbaud NRZ/PAM4 CPO transceiver employing a 1060-nm single-mode VCSEL array and single-mode MCFs. A 2-km MCF link using the transceivers exhibits a BER of ...
Abstract: High-precision alignment between the wafer and mask is crucial for efficient lithography manufacturing. This study introduces a novel alignment mark combining a circular grating with ...
