Optoelectronic Oscillators (OEOs) are devices capable of generating high frequency, high spectral purity electrical signals. These devices utilize both electronic and photonic components. Properties of the latter create opportunities to improve spectral parameters and distinguish single operating frequency. Dual-loop OEO is one of possible configurations to achieve abovementioned goal. The mix of electrical and photonic technology in such devices causes however several analysis issues. Most frequent approach involves circuit-based analysis, which cannot provide sufficient information on the operating frequency and output power. In this paper we present an open-loop analysis of dual-loop OEO and its comparison with experiment results.

“…The abovementioned condition is mostly connected with the phase characteristics of the optical link which can be changed using both electrical and optical methods. Most significant ones involve phase shift over wavelength of the laser and can be obtained using optical fiber with high slope of chromatic dispersion characteristics [12], fiber Bragg gratings [8], [17], [18] or by combining both of these techniques.…”

In this paper we present a brief explanation of comb Optoelectronic Oscillators (OEO) with frequency control and tuning based on the use of fiber Bragg gratings (FBGs). In our approach for frequency control we use a set of fiber Bragg gratings of various resonant wavelengths as an optically tunable delay line that sets the frequency grid of optoelectronic-oscillator. The OEO itself is described by scattering matrix parameters in open-loop configuration.

“…This type of structure has found an application in the opto-electronic oscillators where it can operate as a phase shifter (Fig. 5a) in configuration shown in [30,31]. The principle of operation is based on the discrete control of the group delay with the use of the adjustment of the TLS laser wavelength (TLS -Tunable Laser Source).…”

Abstract. In this paper research on the development of the fiber Bragg grating (FBG) technology which has been conducted at the Institute of Electronic Systems (IES), Warsaw University of Technology (WUT) since 2004 is presented. In particular the directions in the development of advanced set-ups employing the phase mask inscription scheme are discussed and supported with the descriptions of structures designed and fabricated with the use of the laboratory stages constructed at the IES. The novelty of the presented solutions is based on the combination of numerous techniques of the external modification of the interferometric patterns (projected onto cores of photosensitive fibers to modulate their refractive index) as well as application of the modification of the internal properties of the waveguides themselves by the means of introducing strain or tapering.The development of these sophisticated set-ups resulted in the inscription of FBGs with precisely designed spectral characteristics which found application in telecommunications and sensor technology are also illustrated here.The paper is summarized with the specification of the most important achievements attained at the lab and drafting of the possible directions of further research.
