摘要
介绍２×２光纤耦合器的原理和制作，采用３ｄＢ光纤耦合器进行级联实现了８×２．５Ｇｂ／ｓ时分复用器，信号源采用增益开关量子阱ＤＦＢ激光器，脉冲宽度为４０ｐｓ，周期为４００ｐｓ。
The principle and its fabrication of 2×2 optical fiber coupler have been introduced in this paper.By utilizing 3 dB optical fiber directional coupler and concatenated, we fabricated 8×2.5 Gb/s optical time division multiplexer.The optical pulse source is a gain switched quantum well DFB laser, which generates pulse with width 40 ps and period 400 ps.
