Accurate Power-Efficient Format-Scalable Multi-Parallel Optical Digital-to-Analogue Conversion
Photonics, 2021 In optical transmitters generating multi-level constellations, optical modulators are preceded by Electronic Digital-to-Analog-Converters (eDAC). It is advantageous to use eDAC-free Optical Analog to Digital Converters (oDAC) to directly convert digital ...

Theoretical study of implementing an all-optical analogue-to-digital conversion based on the Mach–Zehnder interferometric configurations [PDF]
, 2010 A new technique of ultrafast analogue-to-digital (A-D) conversion for an all-optical data processing is proposed. This technique is based on the Kerr nonlinearity-induced cross-phase modulation in single-mode Mach–Zehnder interferometer configurations ...

Comparison of single- and double-sided pulse width modulated signals with non-linear predistortion
, 2012 Class D amplifiers are based on a low-bit pulse width modulated (PWM) signal reconstructed through the lowpass characteristic of the loudspeaker. To create a PWM signal, a non-linear conversion from a standard pulse code modulated (PCM) signal has to be ...
