Vertical-Cavity Surface-Emitting Laser (VCSEL) diodes emerged in 1999 into very significant commercial use, more than 20-years after the initial baseline research. The VCSEL laser concept derives from the early strained-lattice research of Dr. Kenichi Ida and his students at Tokyo Institute of Technology 1979-80.

The underlying demand for a VCSEL-based capability, however, was not yet ready (in the 1980s to early 1990s) to support commercial operations. This resulted in an evolutionary “fits and starts” period of organization, dissolutions, restructuring, reformation and other turmoil.

United States military weapon system planners in the late 1980s foresaw a far future need for many-orders-of-magnitude greater data transport than was feasible at that time; to be accomplished in very little physical space and being rugged enough for operation in severe environments. It appeared that single-diode edge emitter capabilities could not be pushed up enough to meet the need.

The nature of the struggle to bring VCSELs to a viable market position may be inferred from the “Genealogy of VCSELs” chart constructed by ElectroniCast Consultants.

ElectroniCast provides this one-page chart for clients that want to keep information regarding this important part of advanced photonics history in their archives.
