Manufacturer:MOT 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. |
