SPICE modeling of laser diodes
For simulation purpose a laser diode can be modeled by the subcircuit shown below. The circuit elements represent the unwanted parasitic inductance, capacitance, and resistance which exist in
Laser Diodes
ROHM offers laser diodes (LDs) for Light Detection and Ranging (LiDAR). This application note will introduce ROHM''s LD line-up and show how to design the drive circuits of ROHM LDs.
Laser diode protection circuit
The present invention relates to a laser diode (“LD”) protection circuit, and more particularly to a circuit for protecting a laser diode from an initial instantaneous surge current.

The SRL protection circuitry functions by stopping the current for ~0.5 ms whenever there is a sudden change in the resistivity of the diode. When driven by a constant current source, the resistivity is
Protecting Diode Lasers from Electro-Static Discharge (ESD)
Diode lasers are very reliable under normal operating conditions. However, like most semiconductor devices, they can be damaged or destroyed by inadvertent electrical or static discharges (ESD).
Review of ESD Approaches -
In this scheme, a Zener diode is connected anti-parallel with the laser diode. There are several problems with this technique. One problem is that Zener diodes are notoriously slow devices, and are not able
