摘要：

We present a 16-channel waveguide grating router multifrequency laser that can be modulated with a 250-MHz bandwidth, a 50-dB extinction ratio, and constant single-mode behavior, We demonstrate a means for immunizing the single-mode lasing against unwanted backreflections from the integrated modulation amplifier, The laser is especially suitable for fiber dispersion-map measurements.
