“…Thermo-optic (TO) and relevant temperature effects in intensity-modulation (IM) electro-optic (EO) systems may strongly affect the EO response of a crystal [1][2][3]. In the entire EO-modulation system, these effects can be examined via their influence on the position and thermal stability of the operating point over the system's characteristic (transfer) curve [3].…”

“…Then we present investigations of these equations as regards the above parameters along with calculations of the uncertaintities in the determination of temperature coefficients for the effective EO coefficient r, the half-wave voltage V π , and the IM depth m. It is of note that in this publication, the theoretical analysis of the thermo-optic effects in an electro-optic modulation system is only presented. In the experimental field, a determination of various TO coefficients of LiTaO 3 made by the authors, in the case of a transverse EO configuration, has been already published elsewhere [3].…”

In this work, a thermally tunable optical resonator operating in the visible wavelength range is reported, which consists of a bilayer structure composed of a thin silver layer and a dielectric coating of [Fe(HB(1,2,4‐triazol‐1‐yl)3)2] switchable spin‐crossover (SCO) molecules. White light is coupled to the resonant structure using a prism and the resulting resonance spectra are investigated as a function of the incident angle and temperature. Switching the SCO molecules from the low‐spin to the high‐spin state gives rise to a substantial blueshift of the resonances reaching up to 30 nm (associated with a reflectance modulation of up to 70%), which can be linked, through transfer‐matrix simulations, to the variation of the optical thickness of the molecular layer. Interestingly, the study demonstrated that the large thermal tunability of the device also gives rise to a photothermal nonlinearity, which can be leveraged for achieving optical limiting applications. Overall, through the present study, it is shown that molecular SCO nanomaterials can be superior to commonly used thermo‐optical switches and well‐established optical phase‐change materials for applications requiring high broadband optical transparency in the visible spectral domain.
