Pulsed laser clocking and quantum pulse gates enable optical ADC conversion with high resolution, low distortion, and no cryogenic cooling.
- Coherent Photonic Monobit ADC With Optical Dithering for High SFDR
Optical dithering and coherent detection help a photonic monobit ADC raise sampling rate while reducing spurs and power use.
- Optical DAC Modulator Segmentation for Precise Low-Power Conversion
Independently addressable optical modulator segments enable precise digital-to-analog conversion with lower power and less circuit complexity.
- Optical Sensor Array Layout for High-Resolution Encoder Interpolation
CMOS sensor arrays matched to each interpolation period cut ADC complexity while preserving high-resolution optical encoder precision.
- Photonic ADC Architecture Using Phase Modulation to Cut Energy Use
Phase modulation and optical interference replace energy-hungry electronic sampling, enabling lower-power analog-to-digital conversion.
