Observation of Microcavity Modes and Waveguides in InP Nanowires Fabricated by Selective-Area Metalorganic Vapor-Phase Epitaxy

摘要

Hexagonal cylindrical InP nanowires with a wurtzite structure were fabricated by selective-area metalorganic vapor-phase epitaxy (SA-MOVPE).The microcavity modes and waveguides in InP nanowires were investigated by photoluminesence (PL) spectra.Optical mode analysis for InP nanowires with different lengths reveals the axial Fabry-Perot cavity in InP nanowires,which were formed between the two end facets of nanowires.In addition,T-branch subwavelength guiding and optical coupling in InP nanowires were observed.
