Hi I am using ring modulator example for passive ring resonator construction.(Ring modulator ÔÇô Lumerical Support).
The loss is in dB , I want losses in dB/cm.
The loss in MODE simulation is less for both straight and bend waveguide.
While for same example I saw around 24dB in interconnect . The input power in ONA is in 0dBm.

Could you tell me , what is the propagation loss in ring modulator example (I ran the script for passive waveguide, hence only 0V).
In same example as I seen loss as 24dB, then what is its value in dB/cm?
