Analog-digital conversion of optical signals by means of ring waveguide microresonators

We propose the fast method of analog-digital conversion of optical signals with the use of waveguide ring resonators of micron size. The results of calculation are presented that allow optimization of the parameters of such optical analog-digital converter (ADC) for specific applications. Such optical ADC is capable to operate with the conversion frequency above 109 counts per second in a broad spectral range
