“…Hitherto, several optical/optoelectronic A/D conversion approaches have been proposed and demonstrated, which include the Mach-Zender interferometer A/D converter [36,37], the optical fibre temporal-spectral mapping A/D converter [38], the optoelectronic thyristor A/D converter [39] and the optical alternating layer A/D converter [40]. However, these designs are either optically or electrically complex or cannot be easily integrated.…”

In this paper, we report on the development of the self-collimation phenomenon in photonic crystal structures for integrated optics applications. In addition, detailed numerical analysis, design procedures, fabrication and characterization techniques are included. Applications presented in this paper include: channelless waveguiding, orthogonal bending of light, tunable beam splitter, all-optical analog-to-digital converter, reconfigurable optical switch, chemical/gas sensor and a three-dimensional optical interconnect bus.

“…Optical sampling has also been performed using the photoconductive property of photodiodes [29], [30]. Other optical quantization schemes involving all-optical nonlinear devices [31]- [34], symmetric self-electrooptic effect devices (S-SEEDs) [35], opto-electronic comparators [36], distributed phase modulation [37], and diffractive optics [38] have been investigated. Photonic ADCs based on optical oversampling techniques, such as delta-sigma ( -) architectures, have also been reported [39], [40].…”

Optically sampled analog-to-digital converters (ADCs) combine optical sampling with electronic quantization to enhance the performance of electronic ADCs. In this paper, we review the prior and current work in this field, and then describe our efforts to develop and extend the bandwidth of a linearized sampling technique referred to as phase-encoded optical sampling. The technique uses a dual-output electrooptic sampling transducer to achieve both high linearity and 60-dB suppression of laser amplitude noise. The bandwidth of the technique is extended by optically distributing the post-sampling pulses to an array of time-interleaved electronic quantizers. We report on the performance of a 505-MS/s (megasample per second) optically sampled ADC that includes high-extinction LiNbO 3 1-to-8 optical time-division demultiplexers. Initial characterization of the 505-MS/s system reveals a maximum signal-to-noise ratio of 51 dB (8.2 bits) and a spur-free dynamic range of 61 dB. The performance of the present system is limited by electronic quantizer noise, photodiode saturation, and preliminary calibration procedures. None of these fundamentally limit this sampling approach, which should enable multigigahertz converters with 12-b resolution. A signal-to-noise analysis of the phase-encoded sampling technique shows good agreement with measured data from the 505-MS/s system.

“…The inversion channel devices offer a significant advantage in this respect. In previous published work [10]we have reported the operation of a smart comparator based on the thyristor. This was used to obtain functional operation of a 4 bit AD converter with the configuration shown in Fig.8 which is operated as a nyquist rate converter.…”
