Laser Diode Modulation and Noise

Welcome to Scribd!

Current bias can be set from 0 to mA with a manual potentiometer. A jumper allows to choose between 3 modulation gains. The figure below shows the current noise of the different DRV laser driver variants operated at a maximum rated current:.

The figure below shows the current evolution of the mA laser current version driver A delivering mA over 40 hours. The DC modulation input controls the current setpoint. It combines large bandwidth and high linearity. Modulation performance are characterized using a DFB laser. Large and small signal correspond to a modulation signal of 2 V pp and mV pp , respectively. Products Blog Support. Compliance voltage 6V supply 3. More Laser drivers. New options. Current stability The figure below shows the current evolution of the mA laser current version driver A delivering mA over 40 hours.
