Number of bits per pulse width in buffers and delay lines (optical)

Click For Summary
SUMMARY

This discussion focuses on determining the corresponding storage bit for an optical delay line when a pulse is delayed by 10 pulse lengths. The user is simulating a CROW type delay line using CST Microwave Studio and employs a Gaussian pulse for excitation. The normalized delay is calculated by dividing the delay time by half of the input pulse width. Key considerations include the nature of the input signal and whether the delay line operates in a single or dual clock domain.

PREREQUISITES
  • Understanding of optical delay lines
  • Familiarity with CST Microwave Studio
  • Knowledge of Gaussian pulse characteristics
  • Concept of clock domains in digital signal processing
NEXT STEPS
  • Research the principles of CROW type delay lines
  • Explore simulation techniques in CST Microwave Studio
  • Learn about the impact of pulse width on delay line performance
  • Investigate clock domain synchronization in digital systems
USEFUL FOR

Engineers and researchers working with optical delay lines, signal processing specialists, and anyone involved in the simulation of photonic systems.

Hi

I was working on delay-lines and I wanted to know if a pulse is delayed by 10 pulse lengths through a delay-lines than what is the corresponding storage bit for that delay line.

Thanks

Could you give some examples of the types of delay lines you are looking at? Some of the words you used in your post are confusing to me. What is the clocking system for the delay line? What is the nature of the input signal to the delay line? Are these digital delay lines or analog delay lines? If digital, are the input and output digital signals in the same clock domain, or in two different clock domains?

It is an optical delay line. I have attached a sample paper. I am simulating the CROW type delay line in CST Mirowave Studio.

I use a Gaussian pulse to excite the structure and measure the time corresponding to the maximum value of the signal at the output. I divide this time with the time corresponding to half of the input pulse width, to obtain a normalised delay in terms of pulse width.

Thanks for your interest.
