Abstract

In this paper, an integrated all-optical high precision (well below 0.01 ^0C ) temperature sensor based on ring resonators implemented by GaAs and InP is proposed. Analytical relations illustrating the effect of temperature on the intensity transfer function and group delay are proposed. The index of refraction and length of the ring are changed due to applied temperature. Based on the derived relations the effects of temperature on the output quantities are illustrated. The output intensity and group delay can be used as suitable quantities for measuring of the applied temperature. In this analysis matrix formulation of the light propagation through networks including ring resonator is used. The obtained analytical relations are evaluated and simulated numerically. Based on our proposed method, it is shown that the proposed technique supports ultra-high precision measurement. Our calculation and simulations show that based on the proposed structure so sensitive sensor can be implemented easily using GaAs and InP as suitable material for manufacturing of ring resonators.
