Optical Sensing
A wide range of optical spectral coverage and flexible power levels enables usability within a wide range of applications
DAYY Photonics’ tunable light sources are designed to measure key parameters such as relative intensity noise (RIN) and device stability. Our Amplified Spontaneous Emission (ASE) sources are ideal for optical sensing, offering a broadband spectrum, unpolarized output, and low-coherence performance.
Meanwhile, DAYY’s superluminescent diodes (SLEDs) combine the spatial coherence of laser diodes with the temporal coherence of LEDs, delivering broad spectral coverage and flexible power levels. This versatility makes them perfect for a wide range of optical sensing applications.
Our light sources possess the ability to increase the sensitivity and spectral reach of fiber sensors that detect pressure, strain, and temperature.
Both the power and wide wavelength range of our sources allow many sensors on different wavelength channels to be multiplexed for multipoint/multiparameter sensing through an optical fiber network.
Our light sources have high spectral density and low unevenness to enable measurement of more attenuated devices over a wider band.
The SLED source characteristics of temperature insensitivity, broad emission wavelength, and high power enable the use of these fiber optic sensors for strain measurements for structural health as well as temperature and pressure sensors in hostile environments.
