Scheme of the experimental setup with 3 detection channels. Channel I is for real space images, Channel II for dispersion measurements, and Channel III for interference experiments. (b) Spatially resolved image of the sample surface emission collected with the setup and imaged on the CCD camera. (c) Spectrally resolved image of the FP of the microscope objective. The part inside the white rectangle is enhanced for clarity.
(a) Spectrally resolved resulting interference pattern for a sum of emitters excited in between and on the sides of the two slits with an excited area of . (b) Interferences recorded for a sum of emitters out of the slits. (c) Blurred interferences for a sum of independant emitters in between the slits.
Evolution of the fringes’ visibility as a function of the spot size w (red dots). The inset sketches the laser shape on the sample surface with the selected region by the two slits. The blue line displays the calculated evolution of the visibility for a propagation length fixed at .
Evolution of as function of for different distances between the slits. (black solid line), (red dashed line), and (blue dashed-dotted line).
