Abstract

Three-dimensional finite-element-method simulations are used to investigate a system consisting of a subwavelength silicon microdisk cavity for the detection of different viruses of the same type. This is done by observing the effects that a spherical nanoparticle had on the frequency resonances of WGMs of the silicon microdisk. Results show that the observed spectral shift vary for the TM15 mode with an attached nanoparticle of radiuses between 100-300 nm. This frequency shift size-dependence makes it possible the for mature and immature HIV-1 viruses to be identified by the resonant frequency change in the transmission spectrum.
