    "abstract": "We theoretically discuss one-photon and two-photon double-slit interferences\nfor spontaneous and stimulated parametric down-conversions. We show that the\ntwo-photon sub-wavelength interference can exist in a general spontaneous\nparametric down-conversion (SPDC) for both type I and type II crystals. We\npropose an alternative way to observe sub-wavelength interference by a\njoint-intensity measurement which occurs for only type I crystal in a higher\ngain of SPDC. When a signal beam injects into the crystal, it may create two\ninterference patterns by two stimulated down-converted beams, showing no\nsub-wavelength interference effect.",
