Determination of power reflectivity of quasi-graded distributed Bragg reflectors using stopband width

Determination of power reflectivity of quasi-graded distributed Bragg reflectors using stopband width

The authors examine the reflectivity of the quasi-graded distributed Bragg reflector using the stopband width. The stopband width of about 1000 AA for a reflectivity of about 99% is able to be measured with an accuracy of +or- 1 AA. Thus, the reflectivity is determined with high accuracy from the st...

Zusammenfassung:The authors examine the reflectivity of the quasi-graded distributed Bragg reflector using the stopband width. The stopband width of about 1000 AA for a reflectivity of about 99% is able to be measured with an accuracy of +or- 1 AA. Thus, the reflectivity is determined with high accuracy from the stopband width. It is found that the quasi-graded distributed Bragg reflector is a high-quality reflector with high reflectivity and low resistance.< >
