“…Although the transmission rate is low but can be improved in future work. We can be using a new material and optimize router design for high performance in all optical devices and nano scale optical systems (Ji et al 2020;Rastgou et al 2018;Mokri and Mozaffari 2019;Yin et al 2020;Mozaffari et al 2019).…”

In the advanced plasmonics integrated circuits (PICs) there has been outstanding, continuing interest in developing routers to harness light-matter interactions in nanoscale dimensions with wanted optical properties. In this regard, herein, we introduce an all-optical router based on nanometer ring resonator which surface plasmon resonance (SPR) and nonlinear materials are used simultaneously to enhance high performance range. By changing the radius of the ring resonator and the intensity of the light we achieved control of the parameters and the routing. The results of routing and shifting the central frequency with light intensity and radius of the ring resonator are studied. The performance of the router indicates that a ring is required for each ports, which changes the control parameters to change its central frequency, as well as we can be said the use of switches and filters as other design features. These routers have advantages such as nano scale size, low light intensity, fast response time, integratable and etc., which are highly used in all-optical circuits, image processing and today's modern technology. In our simulation, we consider transmission or reflection of light in each ports based on the finite difference time domain (FDTD).

“…Tsuji et al (2019) demonstrate that using optical forces, nanoparticle flow can be controlled in all-quartz glass nanoslit channels. Yin et al (2020) have also proposed a plasmonic nanoparticle router, which consists of a series of gold nanostrips on top of a continuous gold thin film, to transport trapped nanoparticles along designated routes in a microfluidic channel with a continuous flow under the incident unfocused light.…”

Since their inception, optical tweezers have proven to be a useful tool for improving human understanding of the microscopic world with wide-ranging applications across science. In recent years, they have found many particularly appealing applications in the field of biomedical engineering which harnesses the knowledge and skills in engineering to tackle problems in biology and medicine. Notably, metallic nanostructures like gold nanoparticles have proven to be an excellent tool for OT-based micromanipulation due to their large polarizability and relatively low cytotoxicity. In this article, we review the progress made in the application of optically trapped gold nanomaterials to problems in bioengineering. After an introduction to the basic methods of optical trapping, we give an overview of potential applications to bioengineering specifically: nano/biomaterials, microfluidics, drug delivery, biosensing, biophotonics and imaging, and mechanobiology/single-molecule biophysics. We highlight the recent research progress, discuss challenges, and provide possible future directions in this field.

“…However, due to the large volume of the traditional desktop laser and vacuum chamber [23][24][25][26], as shown in Figure 1, the optical force-sensing systems mentioned above are only suitable for high-precision measurement in the laboratory environment rather than compact engineering devices. This paper considers the miniaturization of the optical force accelerometer as the main subject of its study.…”

In recent years, the optical accelerometer based on the optical trapping force effect has gradually attracted the attention of researchers for its high sensitivity and high measurement accuracy. However, due to its large size and the complexity of optical path adjustment, the optical force accelerometers reported are only suitable for the laboratory environment up to now. In this paper, a miniature optical force dual-axis accelerometer based on the miniature optical system and a particles cavity which is prepared by Micro-Electro-Mechanical Systems (MEMS) technology is proposed. The overall system of the miniature optical levitation including the miniature optical system and MEMS particles cavity is a cylindrical structure with a diameter of about 10 mm and a height of 33 mm (Φ 10 mm × 33 mm). Moreover, the size of this accelerometer is 200 mm × 100 mm × 100 mm. Due to the selected light source being a laser diode light source with elliptical distribution, it is sensitive to the external acceleration in both the long axis and the short axis. This accelerometer achieves a measurement range of ±0.17 g–±0.26 g and measurement resolution of 0.49 mg and 1.88 mg. The result shows that the short-term zero-bias stability of the two orthogonal axes of the optical force accelerometer is 4.4 mg and 9.2 mg, respectively. The main conclusion that can be drawn is that this optical force accelerometer could provide an effective solution for measuring acceleration with an optical force effect for compact engineering devices.
