Optical Characterization
Understanding how materials interact with light is essential for the development of new photonic technologies. By studying properties such as absorption, transmission, reflection, photoluminescence, and nonlinear optical response, researchers gain valuable insight into the behavior and performance of semiconductors, nanomaterials, optical coatings, and photonic devices. Broadband tunable and ultrafast laser sources enable precise wavelength-dependent measurements, supporting both linear and nonlinear optical characterization across a wide spectral range.
Plasmonics
Plasmonics explores how light interacts with metallic nanostructures, enabling the confinement of light far below the diffraction limit. These enhanced light-matter interactions have created new opportunities in sensing, imaging, spectroscopy, energy harvesting, and integrated photonics. Tunable laser sources allow researchers to precisely excite plasmonic resonances and investigate optical phenomena at the nanoscale.
Tunable lasers allow precise wavelength control for optimising surface plasmon excitation.
Nanophotonics
Nanophotonics investigates the control of light at dimensions smaller than its wavelength, enabling enhanced light confinement and stronger light-matter interactions. By combining photonics, nanotechnology, and advanced materials, researchers develop innovative solutions for optical communications, sensing, imaging, integrated photonic circuits, and quantum technologies, pushing the boundaries of miniaturized optical devices.

“
Radiantis were very flexible with our requirements and perfectly matched to our technical needs and budget. Radiantis OPO has enabled us to carry out advanced optical characterisation of our systems across the UV, Visible and IR, and has proven to be a very reliable and easy-to-use system, delivering high and stable power and fast automated tuning across the complete spectral range. Radiantis team were very friendly and provided a professional and comprehensive user training to key researchers in my lab, which enabled us to operate the OPO successfully and reliably over many years.

The wide tuning range of our Radiantis OPO system has allowed us to access wavelength regimes that have enabled a number of nonlinear optics experiments that would otherwise not have been possible. Radiantis have been very responsive and any problems have always been dealt with swiftly, with engineers being sent over to our lab for extended visits whenever required.
