Fourth-order interference is investigated between fluorescent photons from an atom driven by a laser and then laser field itself, and compared with second-order interference. For some consitions the visibility exceeds 50% which is known to be classical limit. Even though a long time has passed since the laser beam drives the atom, the fourth-order interference can exist while the 2nd-order interference disappear for $\Omega/\beta$>>1.

This paper shows through detailed simulations that the length of conventionally designed multimode-interference couplers can be shorted significantly by stepped-width and stepped-index design. For the cross-coupling device, this stepped-design results in 9% or more length reduction.

파동의 기본적인 성질을 이해하는데 있어서 중요한 실험 중에 하나가 Ripple Tank 실험이다. 그러나, 기존의 실험 장치에서 사용되고 있는 광원은 점광원이 아니어서 수면파의 상을 관찰하기가 쉽지 않다. 본 실험에서는 이것을 보완하기 위해 광원으로 레이저를 사용하였는데 그 결과 선명한 상과 함께 기존의 광원으로는 볼 수 없었던 현상까지도 관찰할 수 있었다. (중략)
