Hi I've started the simulation of a vcsel structure with lumerical software. I've got a problem in solution mode I don't know how i can define the quantum wells materials and features for the software .. Let me give you an example of its structure : As the example says i have to use 7 layers in...

Let me give you an example of a conventional vcsel structure ... Suppose I am going to simulate these parameters in COMSOL : p-DBR : (20 periods) - 7.5um x 2.6 um -- material = Al0.625Ga0.375As Spacer (between p-dbr and Quantum well) : 7.5um x 0.23um -- material = Al0.6Ga0.4As MQW : 0.061um...

Tnx. All i want to do is make a simulation of a vcsel structure.. i should change some parameters like QWs in its active region and then i should check the temprature of its active region and its threshold current! I should apply voltage to the top and the bottom contancts which i should put in...

tnx for your attention yes , I've been studying about vcsel laser for a year and i know its' structure the problem is i don't know how can i simulate the structure! in vcsels we got substrate , bottom dbr , active region , top dbr (im supposed to use hcg structure instead) , and contacts... ive...

Tnx well i think i have to change my question .. does anybody know with which simulators i can simulate a vcsel laser ? i have installed Rsoft , Comsol , FDTD and Silvaco on my computer i have to give some conclusions like thermal , threshold current and the gain of this laser is there anybody...

hi im supposed to simulate a vcsel laser for my thesis i got problem in selecting physics.. i should check its heat transfer and threshold current but i don't know which physics should i choose ! does anyone know about vcsel's physical structure in Comsol ? by the way does anyone know that how...
