摘要
Arrayed waveguide grating (AWG) is a very popular dense wavelength division multiplexing (DWDM) device, which is produced in the field of optical communication technology. Instead of traditional grating and lens spectral system, AWG is used as the spectral chip in miniature Raman spectrometer. It’s quite important for miniature Raman spectrometer in miniaturization and low cost. This paper analyzed the basic principles of AWG device, and introduces the insertion loss, crosstalk and phase error performance parameters, also focuses on the specific technical requirements about wavelength, optical channel number, phase error, wavelength resolution and bandwidth, which are applied in miniature Raman spectrometer. Some new researches and a series of related simulation have been made, finally won the 1 * 40 channels AWG spectral chips, with wavelength range of 880-920 nm, insertion loss of center wavelengths is better than-0.9 dB.
