Homework Statement
Show that the output coupling that maximizes output intensity (Iout=0.5tIsat(2gl/(t+s) -1) is given by t=sqrt(2gls)-s
Homework Equations
The Attempt at a Solution
Iout/Isat=0.5tgl/(t+s)-0.5t
1=0.5tgl/(t+s)-0.5t
1+0.5t=0.5tgl(t+s)
(t+s)+0.5t(t+s)=tgl
this gives me a really long equation. Is it true that for maximum output coupling, Iout/Isat=1?
