How can i calculate this plot (photon energy dependence of the optical gain (or loss = negative gain) of GaAs with the injected carrier density as a parameter?(adsbygoogle = window.adsbygoogle || []).push({});

Show calculated plot based on this equation

Given parameter:

m_{c}=0.067 m_{e}; (effective mass of electrons in conduction band)

m_{v}=0.48 m_{e}; (effective mass of holes in valence band)

T_{2}~0.5 ps; (lifetime for coherent interaction of electrons with a monochromatic field)

E_{g}=1.43 eV; (energy band gap of GaAs)

taung~3x10^{-9}s; (recombination lifetime)

1/m_{r}=1/m_{c}+1/m_{v}; ( reduced effective mass)

n= 3.6: (refractive index for GaAs)

How can i find this value

ħω (energy of photon)- this should be ħω>E_{g}. How can i determine this energy?

λ_{0}

ω_{0}( if i known λ_{0}, can i get ω_{0}? (ω=c/λ))

[ƒ_{c}(ω)-ƒ_{v}(ω)]

Really I need your help. I am new for semiconductor laser. Please any one help me.

Thanks!
