Paper Abstract

We introduce a compound semiconductor based omnidirectional reflector. A four layer pair stack of GaAs/AlAs was grown epitaxially using molecular beam epitaxy, which was then converted to a GaAs/Al2O3 multilayer stack by selective oxidation of the AlAs layers. The resultant one-dimensional photonic crystal exhibited omnidirectional reflection properties in near infrared wavelength range below 1μm. Reflectance spectra measured at various incidence angles and polarizations were observed to be in good agreements with theoretically simulated results.
