Two resonant modes and optimized field amplitude were investigated in silicate microdisk coupled to two straight waveguide using transmission matrix theory. The role of temperature on transmitted intensity showed that the microdisk operation has good thermal stability in the temperature range of -50 to 83 ºC. The transmission intensity is strongly dependent on gold nanoparticle filling factor and its increasing cause to decrease and increase in transmission peak and peak width, respectively.

Keywords: Microdisk resonator, filling factor, through transmission
