Nanoscale optical interferometry with incoherent light.

Optical interferometry has empowered an impressive variety of biosensing and medical imaging techniques. A widely held assumption is that devices based on optical interferometry require coherent light to generate a precise optical signature in response to an analyte. Here we disprove that assumption. By directly embedding light emitters into subwavelength cavities of plasmonic interferometers, ...

Electromagnetic Arbitrary Waveform Generation with Broadband Incoherent Light Sources

I recent years, advances in pulseshaping technology have shown great potential for applications in microwave photonics.1,2 Researchers’ interest is partly motivated by the fact that the generation of arbitrary electromagnetic signals with 1-50 GHz frequency content is a challenge for purely electronic systems. Broad bandwidth signals could have a positive impact on high-speed wireless communica...

Incoherent resonant seeding of modulation instability in optical fiber.

We report control of the spectral and noise properties of spontaneous modulation instability (MI) in optical fiber using an incoherent seed with power at the 10(-6) level relative to the pump. We sweep the seed wavelength across the MI gain band, and observe significant enhancement of MI bandwidth and improvement in the signal-to-noise ratio as the seed coincides with the MI gain peak. We also ...

Semiclassical Theory of Superresolution for Two Incoherent Optical Point Sources

Lord Rayleigh suggested in 1879 that two incoherent optical point sources should be separated by a diffraction-limited spot size for them to be resolved [1]. This criterion has since become the most influential measure of imaging resolution. Under the modern advent of rigorous statistics and image processing, Rayleigh’s criterion remains a curse. When the image is noisy, necessarily so owing to...

Quantum Theory of Superresolution for Two Incoherent Optical Point Sources

Rayleigh’s criterion for resolving two incoherent point sources has been the most influential measure of optical imaging resolution for over a century. In the context of statistical image processing, violation of the criterion is especially detrimental to the estimation of the separation between the sources, and modern far-field superresolution techniques rely on suppressing the emission of clo...
