Yong-Su Kim, Oliver Slattery, Paulina S. Kuo, Xiao Tang
TL;DR
This paper investigates the specific conditions under which two-photon interference occurs with coherent pulses, revealing that temporal overlap is unnecessary but internal coherence is crucial.
Contribution
It establishes that coherence within the same inputs, rather than temporal overlap, is essential for two-photon interference with coherent pulses.
Findings
Temporal overlap is not required for interference.
Coherence within the same inputs is essential.
Provides conditions for classical two-photon interference.
Abstract
We study the conditions for two-photon classical interference with coherent pulses. We find that the temporal overlap between optical pulses is not required for interference However, coherence within the same inputs is found to be essential for the interference.
