用于光网络的可调谐激光器的潜在市场很大，如果预测正确的话，将从2000年的几百万美元扩大到2004年的10亿美元。这一趋势使得几种可调谐激光器的技术之间展开激烈的竞争，而且已经研制出几种实用器件。虽然不断有新的可调谐激光器冲击市场，但密集波分复用（DWDM）技术的迅猛 The potential market for tunable lasers for optical networks is large, and if projected correctly, will expand from a few million dollars in 2000 to one billion in 2004. This trend has led to fierce competition among several tunable laser technologies, and several practical devices have been developed. Although new tunable lasers continue to hit the market, the rapid adoption of dense wavelength division multiplexing (DWDM)
