“…The results of evaluation of the confocal ring resonator samples flat reflective surfaces orientation are shown in Table 2. Using previously modified Fox and Lee method [7,13], it was determined that for the confocal ring resonator considered in this paper, the angular deviation of the reflecting surfaces should be within 5' (worst case considered when the slopes of all reflective surfaces are the same and do not compensate each other). Thus, the resulting deviations from the specified in the orientation of the reflecting surfaces are acceptable.…”

The condition and concept of confocality for ring resonators is considered. The results of the development of a compact (meridional cross-sectional area less than 2 cm2) monoblock ring resonator designed to operate as a sensitive element of an optical gyroscope are presented. A prototype batch of these resonators were studied experimentally. In particular, the shape of the reflecting surfaces of ring confocal resonators and their mutual orientation were measured. The problem of stable input and output of light from monoblock ring confocal resonators and the possibility of their integration into the design of an optical resonator gyroscope are also considered.

“…But the astigmatism of ring resonators (due to the fact that the beam hits reflective surfaces at an angle) complicates their confocal configurations and forces use of aspherical elements. Such resonators can be used as sensitive elements of optical resonator gyroscopes [7,8].…”

“…The lower surface of the prism was clamped. When calculating the distribution of optical fields, the arrays of displacements and mechanical stresses of resonator points are gathered from the model and used as input data in the Fox and Lee method, which was modernized earlier [3].…”

“…It is easy to see from ( 6) that the error caused by the optical Kerr effect is inversely proportional to the effective cross-sectional area of the mode propagating in the resonator. Using the modified method of Fox and Lee [3], the intensity distribution was obtained in the region of the beam waist (on the reflecting surface D) propagating along the sample of a ring confocal resonator (Fig. 7).…”

A sample of a ring confocal resonator designed to operate as a sensitive element of an optical resonator gyroscope is studied. The sample has a monoblock design -the resonator is a single block (prism) with reflective surfaces operating on the effect of total internal reflection. The optical contour of the resonator has the shape of a square with a side length of 10 mm and is formed by four reflective surfaces. Three reflecting surfaces are flat, and one is toroidal with curvature radii in the meridional and sagittal planes that satisfy the confocality condition. The resonator is designed to operate at wavelengths of about 1.55 µm. The advantages of using a of a ring confocal resonator as a sensitive element of an optical resonator gyroscope are analyzed. In particular, it is shown that the reduction of the angular velocity measurement error caused by the optical Kerr effect becomes possible (compared to the use of a waveguide cavity and a whispering gallery mode cavity). The resistance of the system to external influences also improves.
