    "abstract": "We study a general theory on the interference of two-photon wavepacket in a\nbeam splitter (BS). We find that the perfect coalescence interference requires\na symmetric spectrum of two-photon wavepacket which can be entangled or\nun-entangled. Furthermore, we introduce a two-photon wavepacket with\nanti-symmetric spectrum, which is related with photon entanglement and shows a\nperfect anti-coalescence effect. The theory present uniform and complete\nexplanation to two-photon interference.",
