However, because of the chaotic fluctuations and instability of the lasing modes, controlling the lasing properties is challenging. In this study, we use random InP nanowire (NW) arrays that operate in the Anderson localization regime with stable modes as the random lasers. We show that by changing the design parameters of the NW arrays, such as filling factor, dimensions of the NWs, degree of randomness, and the size of the array, the properties of the lasing modes including the number of modes, lasing wavelengths, and lasing threshold can be controlled.Australian Research Council (Discovery Project (DP170102530)).application/pdfen-AU© 2021 Optical Society of America under the terms of the OSA Open Access Publishing Agreement202110.1364/OE.4410032022-04-03OSA Open Access Publishing Agreement
