This dataset contains scanning electron microscopy (SEM) images, Catodoluminescence (CL), MicroPL and Confocal PL measurements and Finite-Difference Time-Domain (FDTD) simulations carried out on InGaN/GaN nanotube microcavities. The samples were fabricated via a combination of Displacement Talbot Lithography for patterning and inductively coupled plasma top-down dry-etching. SEM imaging were used to assess first, the patterning of SiNx mask, and second, the InGaN/GaN nanotube morphology and dimensions. CL were used to assess the optical properties of individual InGaN/GaN nanotube. MicroPL and Confocal PL were used to carry out continuous excitation at room temperature of isolated InGaN/GaN nanotube. FDTD simulations were used to investigate the nature of the resonant modes. Correlation between PL techniques and FDTD simulation suggests that both mixed whispering gallery – Fabry-Perot cavity modes are observed within the single nanotube.
