A laser source driver in 0.18 μm SiGe BiCMOS technology for high speed quantum key distribution

A laser source driver in 0.18 μm SiGe BiCMOS technology for high speed quantum key distribution

Quantum key distribution (QKD) has rapidly developed recently. The repetition frequency of the QKD system increases from tens or hundreds of MHz to GHz. A laser diode (LD) operating in gain-switched mode is widely used as a weak coherent light source in a QKD system. We present an LD driver circuit...
