Hello
I need to know the comparison between the 3 mentioned optical devices in terms of
1- Bandwidth in GHz
2- Silicon area to implement each
3- Sensitivity to heat, how much change in resonance frequency in Hz to 1C change in Temperature
4- Does any of them need specific technology, e.g. 22nm , 14nm, etc. to be implemented
Thanks
For all these devices it is needed to know details about the device to predict the parameters that you are interested in.
For ring resonators they can be as small as having a 3um radius or large with 100um radius. The bandwidth is dependent on the Q-factor, which depending on fabrication quality and coupling region design can be anywhere between 1000-100 000. Similar trade-offs exist for all the other devices (e.g. the more waveguides you include in an AWG the better it will separate closely spaced wavelength, but it then also requires a larger trade-off.
