研究目的
Investigating the synthesis of ultra-high speed waveguide-optical analog-to-digital converter for converting analog information into digital in the gigahertz range.
研究成果
The waveguide-optical ADC allows for the conversion of analog signals into digital in the gigahertz range, with the speed determined by the response time of the electro-optical amplitude modulator and photodetectors. The potential for further speed increase exists if the output signals are used in optical circuits for computing and processing information.
研究不足
The production of the considered ADC can be very expensive due to the need to use optical bistable elements. The simplified version of the ADC uses optocouplers instead of OBE, which may result in slightly lower speed.
