Abstract :
Dual-wavelength Bragg reflectors have been demonstrated using GaAs/AlAs multilayer heterostructures. Desired reflection bands can be obtained by adding proper phase shifters in a GaAs/AlAs periodic multilayer structure. The structure is based on the digital representation of the addition of two periodic functions.
