Tunable Multiwavelength Fiber Laser Using Cascaded Long-Period Fiber Gratings and Variable Optical Attenuator

摘要

We will discuss tunable multiwavelength fiber laser us ing cascaded long-period fiber gratings and variable op tical attenuator. The laser output shows a total of 26 lasing channels and 0.56 nm channel spacing. Simultaneous tuning of multiple wavelengths will be also dis cussed.
