In the second part, the basic principle of theAWG is discussed, then the grating equation of the AWG as well as theangular dispersion, free spectral range (FSR) and frequency response arededuced in theory.

- 因此，許多研究者開(kāi)始研究硅基聚合物 AWG 器件，這種器件具有價(jià)格便宜、工藝簡(jiǎn)單、折射率調整容易、透明性好、偏振不靈敏以及熱穩定性好等優(yōu)點(diǎn)，使其在與無(wú)機材料 AWG 器件的競爭中處于有利的地位。
