FIG. 1.

(Color online) (a) SEM image of the InGaN/GaN microdisk. The inset shows the structure of the disk. (b) PL spectrum recorded from the disk showing the WGMs. Modes with Qs as high as 3500 were measured.

FIG. 2.

(Color online) Mode tuning of InGaN/GaN microdisks immersed in water using (a) 360 nm excitation wavelength with 0.2 mW and (c) 0.9 mW excitation power. (b) 380 nm excitation wavelength with 0.3 mW and (d) 1mW excitation power. The bright lines represent the PL intensity of the different modes.

FIG. 3.

(Color online) PL spectrum recorded after 5 s and 100s during the tuning of the WGMs using (a) 360 nm and (b) 380 excitation wavelengths. The dark red arrows indicate the mode shift.
