“…erformance of microwave photonics (MWP) systems are often strongly influenced by the linearity of optical modulators that convert microwave signals into the optical domain. In particular, the spurious-free dynamic range (SFDR) of the employed optical modulator is the key parameter that determines the performances of such MWP systems as radio-over-fiber (RoF) transmission links [1][2][3], MWP frequency converters [4][5][6], optical beamforming [7], photonic analog-to-digital converters (ADCs) [8] and microwave photonic filters [9], [10]. In recent years, the possibility of achieving MWP functions in a single integrated platform based on Si Photonics is attracting a great amount of research interests [11] and, consequently, the modulation linearity of Si modulators has become an important research topic.…”

Modulation linearity of Si ring modulators (RMs) is investigated through the numerical simulation based on the coupled-mode theory and experimental verification. Numerical values of the key parameters needed for the simulation are experimentally extracted. Simulation and measurement results agree well. With these, the influence of input optical wavelength and power on the Si RM linearity are characterized.

Abstract-In this study, an analytical model for calculating the nonlinear harmonic/intermodulation distortion for RF signals in silicon-based electro-optic modulators is investigated by considering the nonlinearity on the effective index change curve with the operation point and the device structure simultaneously. Distortion expressions are obtained and theoretical results are presented showing that optimal modulator parameters can be found to linearize it. Moreover, the harmonic distortion of a 1 mm silicon-based asymmetric MZI is RF characterized and used to corroborate the theoretical results. Based on the present model, the nonlinear distortion in terms of bias voltage or operating wavelength is calculated and validated by comparing with the experimental data, showing a good agreement between measurements and theory. Analog photonic link quality parameter like carrier-todistortion is one of the parameters that can be found with that model. Finally, the modulation depth is measured to assure that no over-modulation is produced.

“…In this approach, RF frequency mixing for signal up-conversion or down-conversion is performed in a photonic integrated circuit.

“…The following sections 3.3 and 3.4 review two of the above mentioned MWP applications in which we have used a silicon-based electro-optic modulator, explaining more deeply in each case the basic principles and showing our experimental measurements. First, the section 3.3 is devoted to describe and demonstrate experimentally a method for photonic-mixing of microwave signals exploiting the nonlinearities produced by a silicon-based slow-light MZI modulator enhanced via slow-light propagation, which is used to successfully demonstrate an up-conversion process [GUT12C]. Finally, in section 3.4, a photonic-based integrated filter for the processing of RF signals is implemented by a silicon-based simple MZI modulator [GUT13A].…”

“…The measurements of all these published works are verified by simulation results showing the same trend but no closed analytical expressions of the nonlinearities are presented. These results are summarized in the next In contrast with the plain analog signal transport, some nonlinear applications such as mixing or frequency conversion have been demonstrated in the IMWP field [GUT12C]. In these cases, the nonlinear operation of the modulator is exploited, taking advantage of the distortion produced by the nonlinearities.…”

Silicon photonics is one of the most exciting and fastest growing photonic technologies in recent years. The salient feature of this technology is its compatibility with the mature silicon IC manufacturing based on complementary metal-oxide semiconductor (CMOS) processes widely used in microelectronic industry. Another motivation is the availability of high-quality silicon-on-insulator (SOI) planar waveguide circuits that offer strong optical confinement due to the high index contrast between silicon (n=3.45) and SiO 2 (n=1.45). This opens up miniaturization and very large scale integration of photonic devices allowing photonic integrated circuits for a wide range of applications and markets, from optical telecommunications to bio-photonic devices or precise fibre sensors. Optical modulators are key building-blocks for high speed signal transmission and information processing in any photonic interconnection solution. The work developed in this thesis, as part of the objectives of the European project HELIOS in which it is framed, is essentially focused on realizing compact and efficient modulators integrated on silicon chips. The thesis consists of three main chapters as well as the concluding section on the work accomplished. Chapter one is aimed at giving a general description of the benefits of using silicon photonics, showing its challenges and opportunities as well as at giving a deeply overview of all issues related to the electro-optic modulation. Chapter two is devoted to develop silicon modulators with high features for digital applications. Specifically, new optical structures different to the conventional ones are presented with the aim of enhancing the modulation performance or at least several critical parameters in the modulation. Chapter three is dedicated to the analog applications. The concept of microwave photonics is described as well as different researches carried out in the analog scope for application in the field of integrated microwave photonics, all of them using CMOS-compatible electro-optic silicon modulators which validate the potential of silicon photonics as a promising approach for enabling the development of integrated microwave photonics applications. Finally, conclusions on the work realized are provided in Chapter 4.
