Explain about the Homojunction Laser in brief.

Homojunction Laser:

Assume that GaAs be doped with T providing n-type material and with Ge providing p-type material. In forward bias (p-type side is made positive), the majority carriers that is, the electrons into n-side and the holes into p-side are injected across the depletion area into both directions to create a population inversion into a narrow active region. The light produced through radioactive recombination across the band gap is confined within this active region.
