40G速率 DQPSK/IQ铌酸锂调制器, 住友Sumitomo T.SBZH1.5-20PD-ADC, 双驱型
住友Sumitomo T.SBZH1.5-20PD-ADC, 除了支持传统的IQ/QAM调制类型,
双驱型IQ调制器具有更大自由度来实现对子马赫泽德干涉仪的每个臂进行任意相位控制,
以达到精确的相位匹配或者相位差,由此可以激发出更多新奇的应用,诸如光域中的混频
或拍频等ROF的应用,或者实现极高消光比,或飞秒超短的光脉冲输出等等。
40Gbps DQPSK Modulator, Sumitomo T.SBZH1.5-20PD-ADC, Dual Drive IQ Modulator
This optical modulator is a DQPSK Dual-Drive( Quad GPPO) Mach-Zehnder modulator with
modulation speed of up to 22.5Gbaud.
The structure of dual drive MZ interferometers enables exact phase match or arbitrary phase
difference control, which make it ideal for some novel application.
This optical modulator integrates a monitor PD chip and coupler function for automatic bias
control (ABC) for the compensation system of DC-drift and other phenomena.
