“…This is easily realizable with an integrated optical component [2]. By supposing as previously that the power of the LO signal is chosen in order to maximize the mixing power and that the power of the RF signal is low, the power detected at the mixing frequencies after quadratic photodetection can be written as…”

“…The comparison is carried out through a theoretical approach and the BER measurements function of the input optical power.

The BER performances of a classical external optical Mach–Zehnder modulator and a passive all‐optical integrated device, an unbalanced Mach–Zehnder interferometer, are measured and analyzed theoretically. This analysis show better results for the passive all‐optical device than for the external modulator in the case of the laser diode's high enhancement factor. © 2003 Wiley Periodicals, Inc.

“…The cascaded external modulation [2][3][4] can provide large bandwidth, but two external modulators are needed, which leads to low conversion efficiency, large insertion loss and high cost. To solve the above problems, approaches based on a single modulator have been proposed [5][6][7]. In [5], [6], the local oscillator (LO) and RF signals are combined by a microwave combiner and then applied to a direct-modulated LD or a external modulator.…”

A novel photonic frequency downconverter is proposed and demonstrated using a single dual-drive MachZehnder modulator (DMZM). In the proposed scheme, the local oscillator (LO) and radio frequency (RF) signals are sent to the two RF ports of the DMZM, respectively. By biasing the modulator at the minimum transmission point, a downconverted intermediate frequency (IF) signal with the RF and LO components suppressed is obtained. An experiment is carried out to demonstrate the feasibility of the downconverter. Results show that a 30-GHz RF signal with 50-Mbaud 16 quadrature amplitude modulation (QAM) is successfully downconverted to the 2.4-GHz IF band. The error vector magnitude (EVM) of the downconverted signal is less than 2.0%.

“…And there have been rapid advances in the techniques to generate and transport radio signals over optical fiber in recent years (see, e.g., AiRaweshidy and Komaki [2002]). When the wireless channel is in series with the optical link, nonlinear distortion due to the electrical/optical conversion is the biggest concern (see, e.g., Maury et al [1997]). This makes nonlinearity compensation an attractive solution to improve link performance.…”

Abstract:A physical nonlinear dynamical model of a laser diode is considered. We propose a feed-forward control scheme based on differential flatness for the design of input-current modulations to compensate diode distortions. The goal is to transform without distortion a radio-frequency current modulation into a light modulation leaving the laser-diode and entering an optic fiber. We prove that standard physical dynamical models based on dynamical electron and photons balance are flat systems when the current is considered as control input, the flat output being the photon number (proportional to the light power). We prove that input-current is an affine map of the flat output, its logarithm and their time-derivatives up to order two. When the flat output is an almost harmonic signal with slowly varying amplitude and phase, these derivatives admit precise analytic approximations. It is then possible to design simple analogue electronic circuits to code approximations of the nonlinear computations required by our flatness-based approach. Simulations with the parameters of a commercial diode illustrate the practical interest of this pre-compensation scheme and its robustness versus modelling and analogue implementation errors.
