摘要：

The　theoretical　model　of　optical　frequency　comb　based　on　cascaded　intensity　modulator　and　phase　modulator　was　established.　The　relationship　between　the　flatness　of　optical　frequency　comb　and　the　offset　point　of　IM　(βIM),　the　modulation　coefficient　of　IM　(χIM),　and　the　phase　difference　of　driving　signals　of　IM　and　PM　(ΔΦ)　was　analyzed.　The　results　show　that　the　optimum　values　of　ΔΦ　are　multiples　of　π　and　independent　from　other　parameters.　Meanwhile,　the　optimum　values　of　βIM　and　χIM　are　linearly　correlated.　With　the　number　of　the　comb　teeth　increasing,　the　optimum　value　of　χIM　moves　toward　0,　and　the　optimum　value　of　βIM　moves　toward　π　accordingly.　©,　2015,　China　National　Publishing　Industry　Trading　Corporation.　All　right　reserved.
