Advances in the use of MOCVD methods for the production of novel photonic bandgap materials

We describe the use of novel MOCVD methods designed to infill templated str uctures based upon synthetic opals in order to provide increased refractive index contrast necessary for the creation of full photonic bandgap materia ls. The method employed is illustrated by considering the production of str uctures containing III-V material GaP and using this example, we demonstrat e the ability to achieve levels of infill higher than any previously report ed. We describe the use of novel MOCVD chemistry in the creation of a poten tially new class of inorganic material, potentially capable of direct lumin escence from within the photonic bandgap system.
