Optoelectronic device substrates

During recent years, the market for optoelectronic devices has grown rapidly. The major growth segments in the non-communication optoelectronic market are expected to be light-emitting diodes (LEDs) with revenues of $2.1 billion today reaching $3.2 billion in 2003 and lasers increasing from $1.0 billion to $2.1 billion in 2003. In particular, the group III nitrides in the ultraviolet, blue and green wavelength range and the group III antimonides in the infrared range have been developed to a performance level ready for large-scale industrial production. Their contributions to the market growth rates are significant.
