Gain and Loss When light propagates in a gain waveguide, its intensity changes with distance as: Il=I0exp(Gl)Il = I_0 \exp(Gl) Il=I0exp(Gl) Where GGG is optical gain (different for different mod...
Problem Deploy gitalk is very easy in Hexo, but I get in a stupid mistake. After login in GitHub, the web page redirect to home page and raise “mismatch redirect URL”. Solution I am inspired by Git...
Multiple Quantum Well A quantum well is a potential well with only discrete energy values. Multiple quantum well This Figure shows a typical structure of multiple quantum well (MQW). Compared wit...
Introduction of Laser This figure shows principle of a conventional quantum laser where the electrons are bound to atomic, molecular or solid-state energy levels (”bound-electron laser”). Here, la...
