“…Silica-on-silicon and silicon nitride technologies allow the fabrication of resonators with very low loss [41]- [43], but LiNbO 3 [44], glass [45,46], silicon [47], polymers [48], and InP [49,50] are also used. Along with these fully passive ring resonators, some configurations, including an optical amplifier to compensate losses, have been also proposed and experimented [51,52].…”

Low-cost chip-scale optoelectronic gyroscopes having a resolution ≤ 10 • /h and a good reliability also in harsh environments could have a strong impact on the medium/high performance gyro market, which is currently dominated by well-established bulk optical angular velocity sensors. The R&D activity aiming at the demonstration of those miniaturized sensors is crucial for aerospace/defense industry, and thus it is attracting an increasing research effort and notably funds.In this paper the recent technological advances on the compact optoelectronic gyroscopes with low weight and high energy saving are reviewed. Attention is paid to both the so-called gyroscope-on-a-chip, which is a novel sensor, at the infantile stage, whose optical components are monolithically integrated on a single indium phosphide chip, and to a new ultra-high Q ring resonator for gyro applications with a configuration including a 1D photonic crystal in the resonant path. The emerging field of the gyros based on passive ring cavities, which have already shown performance comparable with that of optical fiber gyros, is also discussed.

“…1b). On the basis of such structures various elements of waveguide planar optics may be designed, such as splitters of Y type [36], 1xN splitters [37], multiplexers [38][39][40][41][42], directional couplers [43], ring resonators [44,45], planar polarizers [46], planar interferometers [47,48], gradient structures of multimode interference couplers MMI [49][50][51]. These elements cooperate with fiber waveguides.…”

Abstract. This paper presents the technological aspect of application of the ion exchange method in producing gradient refractive index in glass. The possibility of predictable and repeatable producing of the changes in glass refraction with the use of this method has been presented, as well as the method of in situ control of the process of diffusion doping of glass based on the measurement of the temperature. This method is based on simultaneous (to the carried process) solving the nonlinear diffusion equation modeling the spatio-temporal changes in normalized concentration of the admixture ions in glass. For this purpose the knowledge of temperature characteristics of diffusion coefficients of exchanged ions is used. The result of such control of diffusion processes is information on the current (temporary) refractive index profile of the resulting waveguide. The presented method of control has been confirmed by experimental results, which concern modeling and measurements of planar waveguide structures of slab type. The proposed methodology can also be used to control the diffusion processes of producing another type of two-and three-dimensional gradient structures. According to the author's knowledge the method mentioned above has not been described in literature before.

“…Another example of integrating amplification into device functionality is ring resonator with gain, fabricated into Nd-doped glass by silver ion exchange, which can be used as an optical gyroscope rotation rate sensor. 182 The finesse of a 16 mm diameter resonator increased from 11 to 250, with pumping of the gain medium.…”

Abstract. We review the history and current status of ion exchanged glass waveguide technology. The background of ion exchange in glass and key developments in the first years of research are briefly described. An overview of fabrication, characterization and modeling of waveguides is given and the most important waveguide devices and their applications are discussed. Ion exchanged waveguide technology has served as an available platform for studies of general waveguide properties, integrated optics structures and devices, as well as applications. It is also a commercial fabrication technology for both passive and active waveguide components. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).
