Nano-opto-electro-mechanical (NOEM) oscillator with controllable non-linear dynamics

In this paper, a nano-opto-electro-mechanical (NOEM) oscillator with controllable non-linear dynamics is demonstrated. An optical gradient force driven cantilever shows high non-linearity due to non-linear behavior of the optical force. The non-linear dynamics of the oscillator which utilizes opto-mechanical interaction is well studied and controlled by varying the optical signal, including the power and wavelength. The resonance frequency of the oscillator can be tuned by up to 50 KHz by changing the detuning condition of the opto-mechanical system. It has potential applications such as optical navigation sensors, actuators and optical switches.
