    • 2/dT)=0. Such a particular operating point can be searched for experimentally. In microwave resonators compensation of the temperature dependence of the absolute frequency (not of the difference of two frequencies as above) has been demonstrated both by doping the dielectric with ions and making a composite resonator formed by parts of different materials.

    • Monolithic optical resonators have been used at room temperature for quantum-optical studies starting about a decade ago. These were fabricated from nonlinear-optical crystals such as lithium niobate and potassium niobate. Such crystals typically have substantial loss, and moreover are electro-optic, so they are not suited for the present application. Monolithic resonators made of fused silica were first studied a decade ago [28]. This material is of interest due to the extremely low loss exhibited by ultrapure fused silica. With a 7.5×7.5 mm square monolithic fused silica ring resonator based on total internal reflection (fabricated by REO, Boulder, CO) linewidths of 190 kHz at impedance match at a wavelength of 1064 nm were obtained in our group [29]. This corresponds to a total (absorption plus scatter) loss coefficient ξ=3 ppm/cm. Pipino [30] recently reported on a similar fused silica resonator with a loss for 580 nm light, equivalent to a 240-kHz linewidth at impedance match. In early works on cryogenic optical resonators, a quartz monolithic optical resonator has been operated at liquid helium temperature [31]. This device, however, possessed a dielectric coating of relatively high transmission and thus exhibited a large linewidth.
