Optical Sensors


The group focuses on research and development within optical sensor technology. One branch is practical development of optical sensors and sensor systems for industrial applications. We work on integrated as well as fiber-based sensors, with the near time focus on industrially relevant fiber sensors. Examples include mechanical sensors for wind turbines, chemical and biological sensors for broader applications, and ultra-high sensitivity devices for special applications such as hearing aids and improved vision. The other branch is fundamental research on sensors, where we focus on development of low noise optical sources and amplifiers based on quantum effects.

On a longer time perspective, we do research into improved optical sources and amplifiers for sensors, and integration of these together with the primary sensor devices on optical chips. The final aim is development of sensors with significantly better sensitivity and selectivity suitable for cheap mass production. We also intend to apply novel sources and amplifiers for other purposes such as quantum cryptography.
