Consider an edge-emitting laser with identical facets. Find the mirror loss and threshold gain if nactive =3.2, a,=5 cm·1 and L=l mm. Now consider that one of the facets is coated with a dielectric/metal layer such that the reflection coefficient is R=0.98, find threshold gain and mirror loss for this case and compare with the previous result. Which one do you think will have a smaller threshold current and higher power when the output from the facet with the same R is measured? Why?
