You can use the Poyinting-vector and then integrate it in space, and it gives the same result. PLease refer to this link for more infomration: https:\/\/optics.ansys.com\/hc\/en-us\/articles\/360034397034-Units-and-normalization-conventions-in-Lumerical-solvers&lt;\/p&gt;&lt;p&gt;&lt;br&gt;T=transmission(&#8220;monitor&#8221;); # this function always gives normalized result.&lt;br&gt;f=getdata(&#8220;monitor&#8221;,&#8221;f&#8221;);&lt;br&gt;p_watt_Hz=T*sourcepower(f); #power spectrum&lt;br&gt;P_watt=integrate(p_watt_Hz,1,f); # in Watt&lt;\/p&gt;&lt;p&gt;I hope I helped.
