Paper Abstract

A tunable triple-channel-wavelength fiber laser based on a digital-micromirror-device (DMD) is demonstrated. The DMD processor is controlled by a FPGA system to load grating image to the device storage, and the device driver switches the pixels array to generate reconfigurable reflective digital diffraction gratings on DMD surface. When light irradiates on DMD, corresponding wavelengths are selected and sent to erbium-doped fiber amplifier (EDFA). Hence, a multiple-wavelength laser is generated with laser line - width of 0.02nm. The tunning is fine enough to cover the C-band with a step of 0.08nm and the side mode suppression ratio (SMSR) is larger than 50 dB at room temperature. The switching speed of DMD to generate new gratings on the array is as fast as 1.92 ms.
