Abstract

The ultraviolet quantum catastrophe of the zero-point fluctuations in an L-C circuit of finite Q is revisited. The zero-point energy is shown to approach the value hω₀/2 only in the limit of an infinite Q. A Fabry-Perot resonator, on the other hand, has bounded zero-point energies of its modes that are equal to hω₀/2 . We analyze the noise of an ultra-fast mode-locked laser when the slowly varying envelope approximation (SVEA) is not valid. It is found that quantum correlations exist that are not present in the SVEA. The correlations become evident in the spectrum of the zero-point uctuations.
