英文摘要	A thermo-optic variable optical attenuator (voa) based on a mach-zehnder interferometer and multimode-interference coupler is fabricated. not a single-mode but a multimode waveguide is used as the input and output structures of the optical field, which greatly reduces the coupling loss of the voa with a normal single-mode fiber. the insertion loss of the fabricated voa is 2.52 to 2.82 db at the wavelength of 1520 to 1570 nm. the polarization dependent loss is 0.28 to 0.45 db at the same wavelength range. its maximum attenuation range is up to 26.3 db when its power consumption is 369 mw. the response frequency of the fabricated voa is about 10 khz.
