Laser Doppler vibrometry (LDV) is a non-contact vibration measurement technique based on the Doppler effect of the reflected laser beam. Thanks to its feature of high resolution and flexibility, LDV has been used in many different fields today. The miniaturization of the LDV systems is one important development direction for the current LDV systems that can enable many new applications. In this paper, we will review the state-of-the-art method on LDV miniaturization. Systems based on three miniaturization techniques will be discussed: photonic integrated circuit (PIC), self-mixing, and micro-electrochemical systems (MEMS). We will explain the basics of these techniques and summarize the reported miniaturized LDV systems. The advantages and disadvantages of these techniques will also be compared and discussed.

“…This can be accomplished with gratings Si3N4 upon the SiO2 substrate as grating couplers that are used to couple the probe signal into the waveguide [48,49]. In addition, the layer fabrication process can rely on planner technology, such as lithography and etching [50]. Fig.…”

This study focuses on the Optomechanical bichromatic wavelength switching system as an indirect two-color up-conversion process that relies on optical force and nanorod scattering effects. This system is used to control light coupling between four parallel optical waveguides made of silicon nitride (Si3N4) which form two identical parts. The parallel waveguides with 0.5 µm × 0.5 µm cross-section and 220 µm lengths suspended on a silica (SiO2) substrate embedded with the array of square silicon (Si) nanorods. By mid-IR plane wave illumination, as control light, with different intensities and different wavelengths on nanorods, scattering would increase and result in an improvement in attractive gradient optical force exerted on waveguides. Via bending waveguides toward each other, caused by optical gradient force, two different visible lights, as probe signals, propagating in the first waveguide of each section would couple to the adjacent waveguide. Simulation results reveal that when the distance between the parallel waveguides in the equilibrium position is 100 nm and the intensity of mid-IR light is 1.28 mW/µm 2 total coupling would occur in two situations: 1-when the control light is 4.5 µm, the probe light with 713 nm wavelength is transmitted to the output, 2-when the control light is 3 µm, the probe light with 609 nm wavelength is transmitted to the output. In the first case 1.92 pN/µm optical force is needed to bend each waveguide by 9 nm and in the second one, 1.28 pN/µm optical force is needed to bend each waveguide by 6 nm for total coupling. The efficiency of the coupled waveguides system is %88.6 for 609 nm probe light injection and %96.5 for 713 nm probe light injection.

“…Основное преимущество использования сенсоров с планарными волноводами заключается в их миниатюрности и простоте эксплуатации. В качестве волноводного материала используются полимеры [6,7], кремний [8,9], материалы типа Ta 2 O 5 [10], TiO 2 [11] и другие. В интегрально-оптических планарных приложениях перспективным является использование аморфных материалов, в частности халькогенидных стеклообразных полупроводников.…”

“…В зависимости от типа анализируемых веществ рассматриваются два варианта конструкций. В первом случае изменяется показатель преломления среды над решеточным элементом ввода, например, в газовых сенсорах [5,7,8]. Во втором случае изменяется толщина и показатель преломления волновода за счет адсорбции молекул его поверхностью, например, в датчиках влажности или биосенсорах [9,10,14,15].…”

The operating principle of the optical grating waveguide sensors is considered. The waveguide sensitivity and detection limit of sensors with waveguides of oxide and chalcogenide glasses are compared. The advantages of the grating waveguide sensors with waveguides with a high contrast of refraction indices are shown. The conditions of obtaining a maximum waveguide sensitivity of the grating waveguide sensors are formulated.
