Optical performance of MQWs. Measured reflectance spectra of (a) a bare DBR/MQW and (b) a DBR/MQW/Ti/Au Fabry–Pérot cavity under no applied bias. The insets show the schematics of corresponding structures. The light orange area in (a) indicates the wavelength range shown in (b). c Measured reflectance of the DBR/MQW/Ti/Au Fabry–Pérot cavity as a function of wavelength and applied voltage
