Description
啁啾光纖光柵一般制做于普通單模光纖或是與之兼容的特殊光纖上,且長(zhǎng)度很短,所以附加損耗很小,而且?guī)缀醪皇芄饫w非線(xiàn)性影響,啁啾光纖光柵通常對(duì)信道分別進(jìn)行補(bǔ)償,可以通過(guò)設(shè)計(jì),很方便在色散補(bǔ)償?shù)耐瑫r(shí)買(mǎi)現(xiàn)色散斜率補(bǔ)償,并且還對(duì)放大器的ASE噪聲有附加的濾波功能。容易實(shí)現(xiàn)器件的小型化。
主要特點(diǎn):
可單通道或多通道工作、非線(xiàn)性低、損耗低、全光纖型、無(wú)源偏振不敏感器件
應(yīng)用:
色散補(bǔ)償器、調(diào)鎖模外腔半導(dǎo)體激光 、短光纖激光的整形、濾波器
