Laser control method and circuitry. |
摘要 |
<p>A laser biasing stabilization circuit and method uses the second derivative of the optical light output of a laser with respect to the current through the laser, d<2>L/dI<2>, in a feedback loop to control the laser bias current through the laser. The modulation current in the laser is controlled using a second, average power feedback loop.</p> |
