Abstract The temperature dependence of the whispering gallery modes (WGMs) of self-assembled microbottle resonators (MBRs) made of poly (methyl methacrylate) (PMMA) have been studied. The MBRs are doped with fluorescent cadmium selenide quantum dots (QDs). WGMs of MBRs are found to exhibit a blue shift on increasing the temperature over a wide temperature range. It has been observed that the shifts are linear with temperature over a ~10 nm wavelength range studied here. The observed shifts are stable over several cycles and longer exposure times indicating high photo-stability.
