A linear regression algorithm is applied to a digital-supermode distributed Bragg reflector laser to optimise wavelength switching times. The algorithm uses the output of a digital coherent receiver as feedback to update the pre-emphasis weights applied to the laser section currents. This permits in-situ calculation without manual weight adjustments. The application of this optimiser to a representative subsection of channels indicates this commercially available laser can rapidly reconfigure over 6.05 THz, supporting 122 channels, in less than 10 ns.

通过回归优化实现分组时标波长交换

将线性回归算法应用于数字超模分布式布拉格反射激光器以优化波长切换时间。该算法使用数字相干接收器的输出作为反馈来更新应用于激光器部分电流的预加重权重。这允许原位计算而无需手动调整重量。将此优化器应用于具有代表性的通道子部分表明，这种商用激光器可以在不到 10 ns 的时间内快速重新配置超过 6.05 THz 的频率，支持 122 个通道。
