  We design and fabricate an 8-channel thin film lithium niobate (TFLN)
arrayed-waveguide grating (AWG) and demonstrate the electro-optical tunability
of the device. The monolithically integrated microelectrodes are designed for
waveguides phase modulation and wavelength tunning. Experiments show that the
fabricated electro-optically controlled TFLN AWG has a channel spacing of 200
GHz and a wavelength tuning efficiency of 10 pm/V.
