“…The effect is often encountered in the field of acoustics but also exists in the context of light waves [1], e.g. in laser mode locking [2], heterodyne detection [3], frequency stabilization [4,5], and optical velocimetry [6]. In addition, electro-optic and acousto-optic modulators create frequency shifts enabling beating of light waves observable with modern detectors [7,8].…”

Beating is a simple physical phenomenon known for long in the context of sound waves but remained surprisingly unexplored for light waves. When two monochromatic optical beams of different frequencies and states of polarization interfere, the polarization state of the superposition field exhibits temporal periodic variation-polarization beating. In this work, we reveal a foundational and elegant phase structure underlying such polarization beating. We show that the phase difference over a single beating period decomposes into the Pancharatnam-Berry geometric phase and a dynamical phase of which the former depends exclusively on the intensities and polarization states of the interfering beams whereas the sum of the phases is determined solely by the beam frequencies. Varying the intensity and polarization characteristics of the beams, the relative contributions of the geometric and dynamical phases can be adjusted. The geometric phase inherent in polarization beating is governed by a compact expression containing only the Stokes parameters of the interfering waves and can alternatively be obtained from the individual beam intensities and the amplitude of the intensity beats. We demonstrate both approaches experimentally by using an interferometer with a fast detector and a specific polarimetric arrangement. Polarization beating has a unique character that the geometric and dynamical phases are entangled, i.e. variation in one unavoidably leads to a change in the other. Our work expands geometric phases into a new domain and offers important novel insight into the role of polarization in interference of electromagnetic waves.

“…This results in a trade-off for the choice of the value of T d . A previous work had initiated a similar loop [15], but the long delay ð11 ms) prevented the loop from clearly improving the chirp precision. In this work, as we want locking to occur in less than 1 ms, we implement a delay of 250 ns, i.e., an interferometer optical length of 60 m.…”

“…1 Currently, two principal configurations in tunable ECDLs are the Littrow configuration 2-7 and the Littman-Metcalf configuration [8][9][10][11] and in both the dispersive element is a bulk diffraction grating. In addition, there are also other external cavity configurations which contain different kinds of dispersive elements such as Fabry-Pérot etalon, 12,13 acousto-optic filter, 14,15 electro-optic filter, 16,17 as well as others.…”

The single cavity all-dielectric thin film Fabry-Pérot filter (s-AFPF) has been investigated in this paper as a means of tuning the wavelength in an external cavity diode laser (ECDL), and the means of limiting longitudinal mode hopping has been also investigated. When a TE or TM plane wave irradiates an s-AFPF, a quasilinear relationship is found in a certain wavelength range between the optical intensity peaktransmittance wavelength of s-AFPF and the cosine value of plane wave incident angle at s-AFPF. Based on this feature, we proposed and investigated a configuration with an s-AFPF in an ECDL. By theoretical calculation, a mode-hop-free wavelength tuning range of about 8 nm around 1551.5 nm was achieved. Also, a method in further extending the width of the mode-hop-free wavelength region is proposed and discussed. The ECDL can be used in the application of environmental monitoring, atomic and molecular laser spectroscopy research, precise measurements, and so on.
