We demonstrate a new concept for analog-to-digital (A/D) conversion based on photonic time stretch. The analog electrical signal is intensity modulated on a chirp optical waveform generated by dispersing an ultrashort pulse. The modulated chirped waveform is dispersed in an optical fiber, leading to the stretching of its envelope. We have derived analytical expressions for the stretch factor and the resolution of the system. An analogto-digital converter (ADC) consisting of the photonic time-stretch preprocessor and a 1-Gsample/s electronic ADC is demonstrated. This technique is promising for A/D conversion of ultrafast signals and, hence, for realization of the digital receiver.

“…The implementation of these operations are discussed in the following section. For the digital logic circuits the papers of Lentine et al [2][3][4] and Atanackovic et al [9] discuss the design of digital logic circuits using p-i(MQW)-n and ni(MQW)-n devices respectively, and these circuits will not be discussed here. All other operations are discussed.…”

“…These limitations have caused researchers to examine both the optical and electro-optical domains rather than just the electronic domain. Examples in the literature where photonics have been used to overcome the limitations of electrical interconnect and switching speeds are Bhushan et al [2][3][4] and Cai and Taylor [5]. The use of a Self Electro-Optic Effect Device (SEED) in a time quantised ADC and oversampled ADC has been demonstrated in Refs.…”

This paper describes the design of a very high speed optoelectronic analog digital converter based on a digital division algorithm called SRT division using n-i(MQW)-n Self Electro-Optic Effect Device (SEED) technology. The proposed structure is a pipeline ADC. The SRT algorithm was chosen because it provides a redundancy at each stage of the pipeline. The amount of redundancy is dependent on the radix of the SRT algorithm and the number set chosen. The relation between the SRT radix, number set and the division full range is given in this paper. Also a macro-model for the n-i(MQW)-n device was developed and used to simulate all the circuitry and algorithmic operations needed for the ADC. These included analog addition, analog subtraction and integer multiplication. Based on the developed macro-model and ni(MQW)-n SEED circuit modules a basic unit of the algorithmic ADC was designed. ᭧

“…Examples in the literature where photonics have been used to overcome the limitations of electrical interconnect and switching speeds are described in Ref. [1][2][3][4]. By combining the switching speed of optoelectronic devices with Micro Electro Mechanical Systems (MEMS) technology it is possible to build very high speed, high density optoelectronic circuits which can be integrated into very high data rate, lightweight, low cost fully integrated optoelectronic systems.…”

Differential architectures for both first order error diffusion and also first order sigm-delta modulators are presented in this paper. Techniques required to transform single-ended architectures to differential architectures are discussed which are suitable for implementation in both PIN and NIN SEED technologies. Descriptions of common SEED circuit modules, together with SPICE behavioural simulations are also presented. A feature of the architectures presented is that they can be fully integrated into a single substrate using MEMS technologies. This can be done by incorporating integrated optical waveguides together with MMIC technology. The goal of this work is a fully integrated differential optical oversampling modulator with extremely high resolution and linearity.
