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.

Prof. Connie Jui-Hua Chang-Hasnain, the Chairperson of Berxel Photonics, Won the IEEE Medal of Honor in 2024

Multi-Mode Fiber (MMF) MM-VCSEL transmission has now been widely adopted in data centers and supercomputers. In short, VCSELs play a critically important role in many applications, including optical communications, sensing systems, biophotonics, medical imaging,consumer electronics,and LIDAR with a prjected market value of over $10 billion.The field of VCSELs owes much of its vibrancy to the groundbreaking work of Chang-Hasnain and Kovama.

An In-depth Look At 3D Sensing

Light sources for 3D sensing are usually configured as either flood illuminators or pattern projectors. Flood illuminators provide homogeneous light coverage over a specific angle. They are used in applications like facial recognition and gesture detection where uniform light distribution over the entire field of view is key to measurement accuracy.
