Advancements in the Design and Production of VCELs at AXT

摘要

Aiming at various blooming demands of optical communication, AXT provides high performance and highly reliable VCSELs, including implant, oxide, single mode and array devices. The push toward higher modulation rates, from 1 to 10 Gbps, has led to advances in VCSEL design and production techniques. The reliability of VCESL devices is of prime importance for all new design and is an integral part of the development process. In this paper, we will overview the development activities of high speed VCSELs at AXT and the corresponding device characterization and reliability results.
