What cross-sections are to be used for the waveguides in the final exam and also is it a strip waveguide?
Also, I am Unable to measure waveguide length, because whenever I try to select a waveguide and measure its length, then klayout gives the error - "select one waveguide you wish to measure".
Could you please clarify how we are expected to measure the waveguide path length in this case, or if there is a specific method or tool we should use for this layout?
