Chip Forum 41st Session：Berxel Made a Speech of The Application of VCSEL Chip in the Digital and AI Era
Date: April 11, 2024
Location: Room 103, Micro-Nano Electronics Building, Peking University
Event Name: Chip Forum 41st Session
Topic: The Application of VCSEL Chip in the Digital and AI Era
Abstract：
Vertical cavity surface emitting lasers (VCSELs) are low-cost enabling laser sources for many applications including optical communications, 3D sensing and optical imaging. In this talk, we reviewed berxel’s recent advances and commercialization of high-speed 106 Gbps PAM4 VCSELs for datacom applications and high efficiency VCSEL arrays for 3D sensing applications.
berxel reviewed recent results of high contrast grating (HCG) VCSELs. With a fixed, high selection ratio in polarization, berxel showed a novel polarization structured light 3D sensor with high depth accuracy in scenes with multiple reflecting surfaces. berxel showed that HCG VCSELs exhibit fewer modes, enabling 3~5 times transmission distance over OM3 multimode fibers for 106G PAM4 modulation signal. Finally, berxel also discussed future prospects for advanced applications.
