Abstract
A GaAs/AlAs Bragg mirror with two reflectivity bands centred at 1.3 and 1.55 µm is reported. High reflectivity is achieved in both bands and good agreement is observed between measured and simulated reflectivities. A microcavity structure is proposed that is resonant at both wavelengths. Such structures can be used to enhance the absorption or emission of signals at the two wavelengths.Keywords
