1. Laser Based Sensors

  • Laser Based Sensors are based upon direct and indirect detection of laser light interacting with a target object, which inherently allow for non-invasive measurements with high precision and high accuracy as well as fast response. Thus, demands and challenges for laser-based sensors continue to grow in both science and technology. The topics of Laser Based Sensors subcommittee include laser ellipsometry, laser speckle imaging, laser spectroscopy, laser Doppler vibrometry, laser interferometry, laser light detection and ranging, and laser-based quantum-enhanced sensing.

2. Nanophotonic and Plasmonic Biosensors

  • This meeting brings together early career and established researchers from academia, industry and government in the rapidly advancing field of nanophotonic biosensors addressing the critical needs in health, environment, food, forensics and security. Nanophotonic devices using plasmonic phenomenon, colloidal nanoparticles, metasurfaces, waveguides and their implementations in quantitative analytical platforms, single-molecule sensors, surface enhanced spectroscopy applications, such as Raman, Mid-IR absorption, fluorescent spectroscopy are within the focus of this meeting.

3. Optical Fiber Sensors

  • Optical fiber sensors, in particular those related to safety, security and defense. These will include both point (interferometric, polarimetric, refractometric, and grating based) and distributed sensor. Examples include, but are not restricted to, gyro, current, magnetic field, radiation, bio and chemical, strain, temperature, pressure, vibrations, DAS, OTDR and OFDR.

4. Quantum Sensing

  • Quantum sensors utilize the quantum properties of matter (such as quantized transitions in neutral atoms, ions, and spin qubits) or quantum phenomena (including entanglement between different qubits or degrees of freedom) to measure physical quantities with unparalleled sensitivity, precision, and accuracy. This meeting aims to cover quantum sensing technologies with real-world applications as well as the development of techniques that will advance sensing performance. Topics include: state-of-the-art quantum sensors for timekeeping, inertial navigation, measurements of temperature, strain, or electromagnetic fields; enabling optical technologies to improve the preparation, control, and measurement of quantum sensing systems; advanced approaches that will push the sensitivity beyond the standard quantum limit.

5. THz Sensing

  • Innovations in source and detector technologies, tailored electromagnetic materials, and computational intelligence are making the terahertz spectral region (0.1 - 30 THz) much more accessible for innovative sensing concepts.  This session will feature contributions in all these areas, with an emphasis on exploring how the terahertz region provides unique capabilities to detect and recognize unique signatures.

6. Chemical and Biological Sensors​

  • This meeting will provide a forum to report the latest advances in optical sensors for chemical and biological detection. Technologies such as fluorescence, Raman and infrared spectroscopy, fiber optics, and silicon photonics have all found recent application in chemical and biological sensing. These sensors utilize similar scientific principles to tackle a wide variety of detection challenges across diverse application areas. Applications for these sensors in areas such as environmental sensing, human performance monitoring, continuous medical monitoring, and chemical and biological hazard detection are all a focus of this meeting.
