Continuous separation of nano-sized molecules has great importance in biomedical applications. This paper represents a near-field optical approach to separate nanoparticles using speckle patterns. Near-field random light patterns (speckle pattern) are generated by the repeated coupling and interference of light in nano-waveguide arrays. The movements of 2-µm and 0.5-µm particles are studied under...
This paper presents an electrostatic controlled near-field nano-opto-probe (NOP), which has high potential for nano-particle trapping, transport and release. Infrared light trapping is utilized to avoid possible optical damage to the biological particles. Within the scheme of nano-electro-mechanical systems (NEMS), this NOP combines the advantages of compact integration, precise nm-scale positioning...
Microparticle trapping and manipulation using the optical force in double coupled ring resonator (DCRR) through wavelength tuning is reported in this paper. The DCRR consists of two coupled identical rings, and a waveguide that is side-coupled to the two rings. The microparticles are propelled by optical radiation force and trapped by optical gradient force, which are both generated by the evanescent...
This paper presents a Nano-opto-mechanical actuator, which is driven by optical radiation force. The actuator consists of two waveguides, two identical ring resonators, and an actuator with Bragg reflector. Light is injected into the waveguides and coupled to the Bragg reflector via the ring resonator. The actuator is displaced by the optical force. The achieved maximum displacement of the actuator...
This paper reports a silicon-based micromachined optical power detector with on-chip measurement ability. The optical power is detected by an integrated electron-tunneling displacement transducer, in which optical force is employed as the bridge between optical energy and mechanical energy transition. Compared with the traditional optical power detectors, which are based on photo absorption, the proposed...
A Nano-opto-mechanical pressure sensor using optical force is reported in this paper. The pressure sensor consists of a square diaphragm, a ring resonator and four waveguides. By applying a pressure ranging from 900 kPa to 990 kPa, the output intensity ratio sensitivity of −2.272 /kPa is achieved. Compared with traditional MEMS pressure sensor, the proposed ring pressure sensor has advantages such...
This paper presents a pressure sensor array based on optical force using Nano-opto-mechanical Systems (NOMS). It consists of a deformable diaphragm and a waveguide array. When pressure is applied on the diaphragm, the gap between the diaphragm and the waveguide is reduced. The induced optical force deforms the waveguide and change the optical loss. In the experiment, it measures up to 32 dB optical...
In this paper, an optical switch driven by the optical force is demonstrated based on Nanoelectromechanical system (NEMS) technology. The switch consists of a Mach-Zehnder interferometer (MZI) and a ring resonator. One of the MZI arms is suspended to enable optical switching by optical force induced displacement. The optical force is introduced by injecting a control light into the ring resonator...
In this paper, a Nano-opto-mechanical (NOM) switch is designed, simulated and experimentally demonstrated, using the electromagnetically induced transparency (EIT)-like effects of coupled-ring resonator. The control of the switch is realized by optical force between the silicon waveguide and the dielectric substrate. As the injection pump power increases from 0 to 6 mW, the normalized power of transmission...
