摘要
利用５０５０耦合器以２×２级联的形式研制成功２×２．５Ｇｂ／ｓ、４×２．５Ｇｂ／ｓ和８×２．５Ｇｂ／ｓ光时分复用信号产生系统。用增益开关量子阱ＤＦＢ激光器产生的宽度为１９ｐｓ、周期为４００ｐｓ的光脉冲作为源信号脉冲所进行的实验表明。
?.5Gb/s,4×2.5Gb/s and 8×2.5Gb/s optical time division multiplexing (OTDM) signal generation systems have been developed by cascading 50∶50 couplers in the form of 2×2.The experiment carried out by using laser pulses with a width of 19ps and a period of 400 ps produced by a gain switched quantum well DFB laser as signal pulse source show that the signals produced by the OTDM signal generation systems,which are fabricated by cascading the couplers with precision optical path difference,can satisfy the need of basic application research.
