“…Aside from Kemp-type PEMs, single-crystal photoelastic modulators (SCPEMs) based on LiNbO 3 and LiTaO 3 have been investigated relatively recently. [6][7][8] In this type of device, the time-dependent birefringence of an optical element is electrically induced directly owing its piezoelectricity. However, the geometric and structural effects of optical elements have not received much attention.…”

We propose and design a phononic crystal (PnC) cavity for efficient photoelastic modulation. A strongly confined acoustic field in the cavity enhances light-sound interaction, which results in efficient phase modulation of light. As one of the possible configurations, an acoustic cavity formed in a quasi-one-dimensional (quasi-1D) PnC was investigated. By carefully tuning geometrical parameters, we successfully designed a high-Q cavity mode for a longitudinal wave within a complete phononic band gap. The acoustic Q was calculated to be as high as 9.5 × 104. This enables efficient optical modulation by a factor of 2.5 compared with a bar-type structure without PnCs.

“…This type of stress sensor can be used to detect an applied transverse load and their orientation. [23] There are also many other architectures and principles for optical stress sensors, for example, the electro-optic compensation for photoelastic birefringence in a single crystal, [24] reflectometric frequency-modulation continuous-wave, [25] and the achromatic optical digital speckle pattern interferometry method to detect the stress [26] are also the designs and principles for optical stress sensors in the literature. To meet the everincreasing demand in global market, optical stress sensors will be developed to achieve superior sensitivity and enhanced reliability with a reduced cost in the future.…”

For example, a graphene sensor has been used to detect various gas molecules such as NO 2 . [7] For important healthcare applications, medical devices built with sensors have been used to measure various vital signals such as blood pressure, body temperature, blood glucose, etc. [8] For example, pressure sensors can be used to test the pulse [9] while chemical sensors allowed the measurement of lactate concentration in blood and analysis of sweat composition for the real time physiologic monitoring. [10] Among the various types of sensors mentioned above, stress sensors play an important role in the sensor family. With the rapid development in the Internet of Thing (IoT) and the big data technology [11] in recent years, the use of artificial intelligence (AI) becomes increasingly significant, [12] accelerating the progress in robotics and automation. Because of this, stress sensors are more and more significant for the development of robotic science and AI technology, including artificial skin. [13] In addition, stress sensors can also be applied in photonics, for example microbend optical stress sensor is a typical application. With the advantages presented by microbend optical stress sensors, such as their flexibility, sensitivity, low-cost, and reliability, [14] they can be used in extreme environments, [15] which greatly extends the applied range of the stress sensors. Despite recent advancement of the microbend optical sensors, almost no review to account for the achievements and promote the future development in this area of research is found in the literature. In this review, the theoretical principles and the assembly of typical optical stress sensors are presented. Three physical mechanisms of the bend-loss-based optical stress sensors are introduced. As one type of the bend-loss-based optical stress sensor, the progress of microbend optical sensors for applications in various areas is discussed. The optical stress sensors have already shown potential in a broader spectrum of applications, from healthcare to robotic science. We anticipate that optical stress sensors, in particular microbend optical sensors, will continue to attract attention of researchers globally. This review provides a comprehensive information pack for the community to advance the future development in optical stress sensor. Optical Stress SensorsStress sensors are designed to sense changes in pressure. Traditional stress sensors detect the stress via the Optical stress sensors have been considered to be amongst the most important categories in the development of stress sensors. Recently, the advancement of microbend optical sensors has been playing a pivotal role in the stress sensor development. In this review, the principles and the architectures of the optical stress sensors are reviewed, and the physical mechanisms of the bend-loss-based optical stress sensors are presented. The latest development and applications of microbend optical sensors in key areas are discussed. The authors aim to provide some guidance in the optical sen...

“…These sensors are mostly based on elasto-optic materials, which enable the direct conversion of mechanical stress to a change in refractive index; the mechanical quantity can be measured via the variation of transmitted and reflected light induced by the refractive index change. [1][2] Therefore, elasto-optic materials substantially determine the performance and potential of optical-mechanical sensors and are the key to the research and development of these devices.…”

Elasto‐optic materials have extensive applications, particularly in sensors, filters, and acousto‐optic modulators in optical–mechanical‐coupled devices. Ferroelectric phenomenological theoretical analyses have shown that materials with large ferroelastic responses also have high elasto‐optic effects, and morphotropic phase‐boundary (MPB) ferroelectrics have substantial ferroelastic coupling; thus, a large elasto‐optic effect can be obtained. In this study, guided by phenomenological theories, lanthanum‐modified lead zirconate–lead titanate (PLZT) transparent ceramics close to MPB are successfully prepared using the hot‐pressing method. The elasto‐optic properties of the PLZT transparent ceramics are investigated using the half‐wave stress and the Sénarmont compensator methods. The results indicate that the PLZT ceramics have high transmittance (higher than 70% in near‐infrared) and a large elasto‐optic effect with a stress‐optic coefficient of 10.41 × 10−12 m2 N−1 (approximately three times that of SiO2). Based on these properties, intensity‐ and interference‐type optical‐stress sensors are designed and realized; better anti‐interference ability can be achieved using the interference‐type sensor. These results indicate that PLZT transparent ceramics are promising candidates for optical–mechanical‐coupled device applications. This study also substantiates that transparent ceramics are novel elasto‐optic materials, which uncover new avenues for the development of elasto‐optic materials with excellent properties.
