Paper Abstract

Optical frequency combs (OFC's) are extremely important for optoelectronics to date. They have found a great variety of practical applications. Some of proposed OFCs generation methods apply acousto-optic (AO) devices. The AO devices in such schemes are used either as the element devoted to the OFC phase stabilization or, much less often, they play the role of the key element responsible for optical radiation frequency shifting in the frequency-shifting loop (FSL). In this paper we continue the theoretical examination of new OFC generation method based on joint application of collinear AO diffraction geometry and FSL. This method gives two novel OFC generation schemes. In the first one collinear AO cell is fed by radio-frequency (RF) generator and FSL connects AO cell optical output and input. The second scheme includes not only FSL but also the optoelectronic feedback connecting the optical output of the system with the piezoelectric transducer of the AO cell. In this case the system operates like optoelectronic generator and external RF generator is not needed. The theoretical model is presented for both cases. Each of the systems gives the possibility to generate OFCs in several ways with varying characteristics. The influence of collinear AO diffraction parameters on the generated OFC characteristics such as spectral width, number of spectral components and envelope shape is examined.
