Abstract. This chapter is concerned with the question: how do gravitational waves (GWs) interact with their detectors? It is intended to be a theoretical review of the fundamental concepts involved in interferometric and acoustic (Weber bar) GW antennas. In particular, the type of signal the GW deposits in the detector in each case will be assessed, as well as its intensity and deconvolution. Brief reference will also be made to detector sensitivity characterisation, including very summary data on current state of the art GW detectors.

“…As shown in reference [22], we need not worry about either ε 0 (ωt) or ε 1 (ωt) at this stage because the longitudinal component of the electric field (i.e., E x ) is an order of approximation smaller than the transverse components, which are given by…”

“…Provided that the wave length of the GW is large compared to the wave length of the light signal, we will use the eikonal or geometrical optics approximation to describe the interaction of the light in gravitational waves. The propagation of the electromagnetic waves in the field of gravitational waves was considered many times and we can refer the reader to several papers dealing with this questions in the geometrical optics approximation [7,21,22,23,24,25]. Our subsequent analysis of this problem will be carried out in close analogy with the paper of Sazhin and Maslova [25], where they have considered the structure of electromagnetic field in Fabry-Perot resonator in the field of gravitational waves.…”

Detection of gravity waves by phase modulation of the light from a distant star

We propose a novel method for detecting gravitational waves (GW), where a light signal emitted from a distant star interacts with a local (also distant) GW source and travels towards the Earth, where it is detected. While traveling in the field of the GW, the light acquires specific phase modulation (which we account in the eikonal approximation). This phase modulation can be considered as a coherent spreading of the given initial photons energy over a set of satellite lines, spaced at the frequency of GW (from quantum point of view it is multi-graviton absorption and emission processes). This coherent state of photons with the energy distributed among the set of equidistant lines, can be analyzed and identified on Earth either by passing the signal through a Fabry-Perot filter or by monitoring the intensity-intensity correlations at different times.

“…For example, as stressed in reference [22], its range of validity is not limited to interferometer arms short compared to the GW wavelength. Therefore, according to the formula, a null effect (signal cancellation) happens if the round trip time τ equals the period of the GW, 2π/ω.…”

“…If incidence is instead oblique then a significant damping factor of sin 4 θ comes in, where θ is the angle between the GW direction and the cylinder's axis [24] 8 . This is a severe penalty, and it also happens in interferometric detectors not optimally oriented [22,31].…”
