Optics basics: Coherence | Skulls in the Stars

Almost all of optics had been concerned with first order coherence. The Hanbury-Brown and Twiss results prompted Glauber to look at higher order coherence, and he came up with a

First, however, we have to set up a quantitative description of coherence. U(t) = a cos(φ − ωt). ̄ω. where the terms a(t) and φ(t) may fluctuate randomly (see Fig. 4.1). Figure 4.1: Illustration of

We propose a quantum beam splitter (QBS) with tunable reflection and transmission coefficients. More importantly, our device based on a Hermitian parity-time

PPPS: In quantum optics, coherence properties of light can be of fundamental importance – different states of light lead to different coherence properties, but this is usually

Higher-order correlations in optical fields

We observe high-order photon bunching from a chaotic, pseudo-thermal light source, measuring maximum third- and fourth-order coherence values of 5.87 ± 0.17 and 23.1 ± 1.8, respectively, in

These investigations, as well as the development of lasers and other novel types of light sources, led to a systematic classification of optical correlation phenomena and the complete statistical

In addition to recoil-induced quantum corrections in the emitted light , we expect the coherence of such light to be limited by the high spatial coherence of the electrons. Furthermore, our results

In this paper, we focus on the temporal coherence and the measurement of the corresponding correlation functions in two atomic setups producing near-chaotic light.

In this chapter we extend the conventional x-ray concepts of brightness and coherence, presented in the previous chapter, to higher order and discuss the propagation of

High-order quantum coherence reveals the statistical correlation of quantum particles. Manipulation of quantum coherence of light in temporal domain enables to produce

The higher the degree of first-order coherence, the higher interference visibility we could observe. Although it is named “coherence” and is an intrinsic property of the radiation itself, either
