Circuit Provides Laser Diode Control - 09/19/02 EDN Design Ideas /
(added 1/05) Laser diodes are sensitive to ESD, rapid turn-on currents, and
overvoltage conditions. To address those problems, the simple laser-diode controller
in Figure 1 has several functions. The first part of the circuit comprises an 8.2V
zener diode, D1 that forms the heart of a constant-voltage source for the laser
diode....
Current Sources for Fiber Optic Lasers - AN90 Linear Technology A large group of
fiber optic lasers are powered by DC current. Laser drive is supplied by a current
source with modulation added to the signal. The current source, although conceptually
simple, constitutes an extraordinarily tricky design problem. There are a number of
practical requirements for a fiber optic current source and failure to consider them
can cause laser and/or optical component destruction. This application note describes
ten laser current source circuits with a range of capabilities. High and low current
types are presented, along...
