Simple expression for light output of edge-emitting d.h. l.e.d.s

A relatively simple expression for the output power of edge emitters has been obtained by defining a net loss coefficient averaged over all wavelengths, and using the radiation confinement-factor concept. The model is verified with experimental data from (AlGa)As l.e.d.s of varying stripe contact length. © 1978, The Institution of Electrical Engineers. All rights reserved.
