Opt Lett. 2006 Apr 15;31(8):1130-2. doi: 10.1364/ol.31.001130.

We propose and demonstrate a method for measuring the joint spectrum of photon pairs via Fourier spectroscopy. The biphoton spectral intensity is computed from a two-dimensional interferogram of coincidence counts. The method has been implemented for a type-I downconversion...

We investigate the influence of air holes on phase sensitivity in microstructured optical fibers to longitudinal strain. According to the numerical simulations performed, large air holes in close proximity to a fiber core introduce significant compression stress to the...

Beating the Rayleigh Limit Using Two-Photon Interference.

Physical review letters

Parniak M, Borówka S, Boroszko K, Wasilewski W, Banaszek K, Demkowicz-Dobrzański R.
PMID: 30608849
Phys Rev Lett. 2018 Dec 21;121(25):250503. doi: 10.1103/PhysRevLett.121.250503.

Multiparameter estimation theory offers a general framework to explore imaging techniques beyond the Rayleigh limit. While optimal measurements of single parameters characterizing a composite light source are now well understood, simultaneous determination of multiple parameters poses a much greater...

Adv Mater. 2022 Jan 07;e2108120. doi: 10.1002/adma.202108120. Epub 2022 Jan 07.

Single-emitter plasmonic patch antennas are room-temperature deterministic single photon sources, which exhibit highly accelerated and directed single photon emission. However, for efficient operation these structures require three-dimensional nanoscale deterministic control of emitter positioning within the device, which is a...
