Laser facets reflectivity calculation from measured optical power

  1. May 6, 2014 #1
    Hi Every one,

    I measured optical output power from both laser facets, front facets emits 120 mW and back facets 10 mW. Assuming front facets reflectivity of 30%(for cleaved facets). What will be the reflective of back facets? Please suggest formula and reference this problem.
