摘要 | A system for dynamically adjusting a bias voltage for a laser diode or a light emitting diode is provided. An output voltage of the laser diode is measured and a level of a supply voltage applied to the laser diode is adjusted to change the bias voltage to the laser diode to manage power usage and avoid saturation of the laser diode. Also, a junction temperature of a laser diode may be estimated by mapping a measured output voltage and known current to device characteristic data based on temperature and the supply voltage adjusted in order to bias the laser diode to compensate for a temperature change. Further, data indicating an intensity level of data to be rendered by the laser diode is used to adjust the second supply voltage to bias the laser diode in advance of rendering the data. |
其他摘要 | 提供了一种用于动态调节激光二极管或发光二极管的偏置电压的系统。测量激光二极管的输出电压,并调节施加到激光二极管的电源电压的电平,以改变激光二极管的偏置电压,以管理功率使用并避免激光二极管的饱和。而且,可以通过基于温度和调节的电源电压将测量的输出电压和已知电流映射到器件特性数据来估计激光二极管的结温,以便偏置激光二极管以补偿温度变化。此外,指示由激光二极管呈现的数据的强度水平的数据用于调整第二供电电压以在呈现数据之前偏置激光二极管。 |
