Determining method of the thickness of the distributed Bragg reflector grown by metal-organic chemical vapor depositon
For a vertical-cavity surface-emitting laser (VCSEL)
the epilayer thickness accuracy is very important. The influence of the thickness deviation on the reflection spectrum of semiconductor materials DBR was analyzed using the transfer matrix method. By the influence
a determining method of the thickness of the DBR grown by MOCVD was presented. Based on the approach
the 980 nmVCSEL wafer was grown by MOCVD
in which center wavelength of the VCSEL reflection spectrum is 982 nm. The results show that the method can be used in verifying the thickness of the epitaxy materials and growth parameters of the MOCVD and provide the reliable information for the VCSEL growth.
