It features a flexible package, with the option for an integrated thermoelectric cooler, an adjustable current limiter, an adjustable delay time, and a low noise design. The GN1161-INE3 includes a wide range of features that make it suitable for a variety of laser driver applications.

Working Principle

Laser diodes are usually controlled by a current source, with the desired current being sent through the diode to create light. This current source is typically either a current source or a voltage source. The GN1161-INE3 implements both current and voltage control, allowing it to adjust output power levels with greater precision and accuracy. The current source is referenced to the Vcc voltage, and the voltage source is referenced to the GND voltage.

The GN1161-INE3 implements a particular type of current and voltage control called “floating current and voltage control.” This type of control allows for greater precision in laser power control than other methods. In floating current and voltage control, there is no fixed positive or negative current reference. Instead, the reference voltage is continuously varying. This allows for incredibly precise control of the laser driver output, ensuring that the desired output power is always achieved.

The GN1161-INE3 also features a wide range of other features. These include an adjustable current limit, adjustable delay time, and an integrated thermoelectric cooler. The adjustable current limit allows the user to set a maximum current limit, which can help to protect the laser diode from over-current conditions. The adjustable delay time allows the user to set a minimum delay time between pulses of current sent to the laser diode, which can help to prevent destructive feedback effects. Finally, the integrated thermoelectric cooler helps to keep the laser diode temperature at a stable level.
