Abstract

Driving basic VCSEL technology in the '90, datacom has been the first volume market for various VCSEL products. The downturn in 2001 can be regarded as a point in time, when engineers both from VCSEL manufacturers and nondatacom users started to identify VCSEL technology as a very promising laser source platform for many other applications. Dedicated spectroscopy laser sources based on VCSEL technology, e.g. for oxygen sensing [1], have proven their competitiveness in industrial applications. The most prosepective consumer market of human-machineinterfaces like laser mice has shown the huge potential of the VCSEL technology in low costs, high volume applications, even given extreme technical performance specifications [2]. Just as a consequence, VCSELs are now penetrating into the next potential volume markets, where unique properties of this technology is requested: High power pulsed laser applications, where low cost is a key factor for market entry. In this paper we discuss a suitable semiconductor technology platform, assembly solutions, selected applications and their market potential as well as performance and reliability data. From small footprint of 0.3 mm² and 0.11 mm² peak output powers of 0.7 W and more than 6 W at 850 nm wavelength are shown at 30 &mgr;s and 30 ns pulse widths, respectively.
