FIG. 1.

(a) Schematics of the experimental setup to interfere the infrared thermal radiation from a heated nanowire with its image in a movable mirror. (b) Interference fringes at 300 and for a wide nanowire. (c) Interference fringes at for variable width nanowires. (d) Change in the visibility of the interference fringe as a function of nanowire width and temperatures .

FIG. 2.

(a) Degree of coherence for blackbody radiation and nanowires as a function of path difference between nanowire and its image. The coherence length for blackbody radiation is at and for the wide nanowire. (b) Increase in the coherence length from at to at for a wide nanowire.

Image of FIG. 3.
FIG. 3.

(a) The radiation intensity (radiation signal normalized by emitting area) is highly enhanced for narrower nanowires. (b) Enhanced thermal emission at different temperatures due to charge confinement and increase correlation in narrower nanowires.
