“…Moreover, produced microresonators were easy to handle and so adapted for the following optical studies performed in free space. The first is based on a micro-Raman spectrometer (HR800, Horiba Group), and the second one, called beam waist technique [24,25], was performed on an optical bench to realize a spectral analysis. Whispering gallery modes propagate by total internal reflection.…”

This paper introduces a preview of targeted current research on organic optofluidic materials and devices devoted to 3D photonics microresonators (MRs). First, such an approach takes advantage from a significant know-how on optical simulations of 3D spherical MRs by complementary and coupled ways based on electromagnetism and quantum mechanics principle. Such simulations have allowed to preset the quantization of whispering gallery modes (WGMs) and to define a new formulation of optical caustics in global 3D MRs cavities. Leaning from these simulations, an interdisciplinary approach has been achieved by combining microfluidics techniques and thin layer processes that allowed with flow rates control the realization of 3D droplets MRs of several tens of micrometers in radii. Finally, free-space optical characterizations have been performed on such 3D polymeric MRs by judicious protocols based, respectively, on a modified Raman spectroscopy laser excitation and an adequate direct beam waist optical coupling. Spectral analysis on such 3D MRs of various sizes confirms the excitation of the expected WGMs revealing free spectral range (FSR) and caustics values close to the analytical ones.

“…Nowadays and over the past two decades, integrated photonics based on optical micro-resonators has been developed with different materials and processes (Rabus, 2007;Monte et al, 2010;Isci et al, 2004). The latter are mainly defined by a looping back of the optical wave on itself by way of 2D or 3D geometries (Scheuer and Yariv, 2006;Zebda et al, 2008;Delezoide et al, 2012;Sanogo et al, 2013;Pluchon et al, 2013) entailing then a quantization of the modes characterizing the resonant mechanisms. One could wonder about an analogy or approach to be considered between these devices, even if obviously their physics is based on waves of different nature.…”

The goal of this paper is to study the impact of a differential mass loss or a lack of material (void) directly located into the core structure of matter together with the possibility of measuring its effect by a resonant signal surface at optical frequencies. To this end, the focus has been on the evolution of effective indices or eigenvalues of micro-resonators as relevant models. Specific lack of mass was measured by way of a resonant optical signal principle. Then, specific families of resonators have been designed and shaped with several slits nano-inscribed upon them. The signal resonant light is then characterized by its pseudo-period while considering the whole geometry, taking account of the void; thus, it contains the information regarding the pre-defined recessed volume. The study was carried out first by controlling the deep UV technology onto an organic so as to fabricate the family of slotted micro-resonators before assessing the evolution of the effective index of the system that is inversely proportional to the free spectral range. Experimentally, the design of the measurement platform made it possible to measure the impact of a given lack of material within the cyclic resonators. Experimental measurements have been carried out so as to confirm previous simulations demonstrating a convergence ranging from 0.09 to 0.39%. Accordingly, the relevant results allow us to validate a quantified description regarding the hollowed out volume (or mass recessed within the core waveguide) with regard to the spatial resonant optical signal.

“…These modes appears near the MRs' surface, when light is confined by total internal reflection. Quantified resonances could be observed when the wavelength of the light coupled into the MRs is an integer multiple of the geometrical perimeter [6,7].…”
