个人简介 James Liu is CEO of Ningbo RaySea Technology co., LTD, a VCSEL supplier, focusing on leading-edge technology and high quality products. Prior to co-founding RaySea Technology, Dr. Liu was technical leader & chief laser scientist for technology and quality division of global supply chain at world#1 Network system incorporation. Prior to that, Dr. Liu was senior engineering manager for more than 10 years for world first-class VCSEL fab in USA. Dr. Liu holds various patents in optoelectronic devices and has authored numerous publications on related subjects. He earned his Bachelor of Engineering degree from Zhejiang university in 1989 and his Ph.D. degree of Optoelectronic from Unvi. Of New Mexico, USA in 2005. 摘要 A vertical cavity surface emitting laser (VCSEL) is a type of semiconductor laser. Compared with light-emitting diodes (LEDs) and edge-emitting lasers (EEL), it has many advantages in terms of wafer probe testing; high power efficiency ; ultra-low power consumption; easy to achieve high-speed modulation; easy to couple to fiber; Dimensional arrays; and easy to integrate vertically, etc. Since invented in 1977, VCSELs become the most versatile laser diodes with enormous market potential, including data communications applications, contactless sensing handheld devices, printing, chip-to-chip communications, 3D imaging and gesture recognition, display and automotive communications applications. VCSEL technology has gradually matured in Europe and the United States with the development of the data communication industry in the past 15 years. VCSEL production now ranks second among all types of semiconductor lasers, with annual production of tens of millions, second only to Fabry-Perot (FP) lasers used in optical disk drives in data storage, and is highly likely It will soon become the first. In this presentation, we will discuss the state-of-the-art and the progress of VCSEL technology over the last few years from data communication to new emerging applications in consumer market, focusing on some key challenges from perspectives of reliability and mass production, etc. |
