Manufacturability Of 850nm Data Communication Vcsels In High Volume

Frequently quoted advantages of VCSELs over other optical sources include wafer scale fabrication and testing, low cost, ease of fabricating arrays and ease of fiber coupling. To benefit from these advantages a robust manufacturing process and product demand are needed. Avago Technologies produces a range of single channel and parallel optical link products incorporating 850nm band VCSEL sources operating at up to 10Gb/s per channel. This paper will explore some important factors which need to be controlled for manufacturability of VCSEL devices.
