Özet

A biosensor design based on a photonic crystal nanobeam cavity with an optomechanical positive feedback mechanism is proposed. Design of the cavity and optomechanical sensitivity enhancement method are numerically analyzed and the results show that fourfold improvement is possible without any degradation of the Q-factor.
