EXPLOSIVE GROWTH OF HIGH SPEED NETWORK SYSTEMS
The explosive growth of high-speed networks, like the Internet, is fueling the demand for large varieties and volumes of compound semiconductor devices.  Figure.1 shows the various applications of compound semiconductor devices.  The optical trunk line and lightwave access network markets, for example, use MQW DFB laser diodes, InGaAs Avalance photodiodes, and PIN diodes.  Wireless systems such as mobile telephony, Direct Broadcase Satellite television (DBS), Local Multipoint Distribution System (LMDS), and Wireless LAN consume large quantities of microwave and millimeter wave integrated circuits.
