For Raman scattering studies of absorbing samples, e.g., in resonance Raman spectroscopy, it is frequently important to optimize the concentration and to correct for self-absorption effects on the observed intensities. These question are explored for 90° “transverse” scattering in a 0.1-cm capillary through intensity measurements of resonance Raman bands of ferro-cytochrome c and tris(1,10-phenanthroline) iron (II). It is found that a simple log intensity vs concentration plot provides the extrapolation needed to eliminate self-absorption effects. The optimum concentration is found to correspond to an absorbance per 1 cm of path length of 13 (average of values for the incident and scattered wavelengths) and is independent of absorptivity and of refractive index of the medium. The data are adequately reproduced by a point-scattering model, although different values of the effective light path through the sample are required to fit the self-absorption and intensity vs concentration curves.

Steering electromagnetic scattering by subwavelength objects is usually accompanied by the excitation of electric and magnetic modes. The Kerker effect, which relies on the precise overlapping between electric and magnetic multipoles, is a potential approach to address this challenge. However, fundamental limitations on the reconfigurability and tunability challenge their future implementation in practical applications. Here, we demonstrate a design approach by applying coherent control to a silicon nanodisk. By utilizing an experimentally feasible two-wave excitation, this coherent light-by-light control enables a highly reconfigurable, broadband, and tunable transverse scattering, extending the feasibility of unidirectional scattering in various practical scenarios, including on-chip integrations and optical communications.
