    Abstract

    Based on the Lithium Niobate on insulator (LNOI) platform, an arrayed waveguide grating with a center wavelength of 1 550 nm, 4 channels and a channel spacing of 400 GHz was designed and fabricated, and the edges of the LNOI waveguide was polished. The test results show that the crosstalk between adjacent channels of the arrayed waveguide grating is about -7.5 dB, the channel non-uniformity is less than 0.5 dB, and the center wavelength is 1 551.3 nm, but there is a large insertion loss of about 27.2 dB. The research will play an important role in the development of high-performance LNOI arrayed waveguide grating.
