Abstract
We suggested and analyzed numerically the possibility to double the sensitivity of the optical resonant sensor. To illustrate the suggested approach we calculated the parameters of the sensors based on one and two photonic-crystal coupled cavities. The correspondence between the analytical modelling and numerical simulations was demonstrated. We estimated the allowances for instrumental errors acceptable when manufacturing the suggested device based on the photonic-crystal coupled cavities. We showed the reasons leading to a decrease of the Q-factor of the resonant system consisting of two cavities due to manufacturing errors. The resources of compensation of the errors arising when manufacturing the proposed device were analyzed.
