Application of VCSELs to Radiation-Tolerant Optical Data Links,cations include telecommunications, computer communication and local area networks. In this chapter we will describe an application of VCSELs in a high energy physics experiment called ATLAS [1] at the Large Hadron Collider (LHC), which is under construction at the European Center for Particle Physics in Geneva, Switzerland.作者: 冒號(hào) 時(shí)間: 2025-3-22 18:53
