Abstract

An acousto-optic tunable filter–based wavelength-selection module with features optimized for a wavelength-multiplexed optical scanner (W-MOS) is proposed and demonstrated. The W-MOS produces high-speed multiple scan beams if it is engaged with an agile tunable source with multiwavelength generation capability. In particular, the proposed fiber-connected module features high-speed, low-loss, narrow-linewidth, and single–multiple wavelength selection by means of radio frequency drive signal control for single- or multiple-beam scan operations. The unique module offers input laser beam power control that in turn delivers the desired scanned laser beam power shaping. Experimental results match module design theory and demonstrate a fast 5.4–µs wavelength selection speed, a low (1.53–dB) fiber-to-fiber optical insertion loss, a 5.55–nm 3–dB spectral width, and a 1500–1600–nm agile wavelength operational band.
