| Abstract: | APTF possesses a unique function of optical wavelength tuning for the use of the optical communication WDM technique. BC-AOTF has advantages of both collinear and noncollinear AOTFs at the same time. Optational principle and design method have been presented. A 98% diffraction efficiency at 20 mW, 33 dB side-lobes suppression and a 0.8 nmA spectral line width have been achieved. |
