manufacturer:linear description:the pre-bias control loop may be used to make a simple compensation for changes in the slope efficiency of a laser diode, in order to maintain a constant ex- tinction ratio. typically the slope effi- ciency of the laser diode is inversely proportional to the threshold current, as shown in figure 9 below. therefore the pre-bias monitor current will compensate changes in the threshold current of the laser diode if it is added to the reference voltage on pin imc at a ratio. this ratio may be chosen individually for the spe- cific laser diode and is set by an external r as shown in figure 3 on page 3. thereby the extinction ratio may be maintained at a constant ratio. the varia- tion of the pre-bias monitor current com- pared to the pre-bias current is only /-1% over temperature and supply, en- suring that the performance is not sacri- ficed by changes in this ratio. |
