Abstract The optical characteristics, spectral responses, crosstalk, and temperature characteristics of alignment and coupling between arrayed waveguide grating chip and single mode fibers with different optical channel cross section dimensions are analyzed and discussed in this paper. The results show that the insertion loss of the AWG device increases with the decrease of the optical channel cross section of arrayed waveguide grating chip, and the position error increases with the alignment and coupling between the arrayed waveguide grating chip and the single mode fibers, and the optical tolerance reduces. The spectrum and crosstalk of device are related to its manufacturing process, and the packaging process has little impact on it. The optical wavelength of AWG optical channel increased with the temperature increasing, and the temperature sensitivity coefficient is about 11.27 pm / °C.
