| 英文摘要 | A circuit which improves the linearity of a high power laser diode is disclosed. A electrical diode is coupled to the anode of the laser diode and a filter/bias network back biases the laser diode and forward biases the PN diode. At lower current levels the amount of current flowing through the laser diode is lowered. At higher current levels, rolloff in the PN diode allows more current through the laser diode. The rolloff performance of the laser diode and PN diode mirror each other closely enough to improve the laser's linear performance by 3 dB to 5 dB. |
