Description

Resonance sensors have been shown to be highly sensitive [1], [2]. Their performance is, however, limited by the presence of noise in the signal amplitude and in the resonance position of the resonator [3]. In addition, the need for low linewidth very stable tunable lasers increases cost and limits on chip integration[4]. To overcome both the noise and integration limitations we propose a biosensor based on two coupled DBR laser cavities. We will discuss the expected sensitivity and the effect of temperature stability. Finally, we will show the expected limit of detection for the sensor
