Oulu
Diffractive Optics
The service includes both scalar and rigorous designing of diffractive optical elements.
Monochromatic light sources
Monochromatic light sources (either continuous wave or pulsed) are commonly employed in the characterization of the functionality of optical elements and in a variety of optical measurements.
Polychromatic light sources
Polychromatic light covers a specific range of wavelengths, and it can be used for spectral measurements.
Raman spectroscopy
Raman Spectroscopy constitutes a non-invasive analytical technique that furnishes intricate insights into chemical constitution, phase transitions, polymorphic variations, crystalline characteristics, and molecular interactions.
Refractive index and thin film thickness characterization
The service includes ellipsometry and prism coupler techniques.
Spectral measurements and analysis
The service includes various spectral measurement and analysis methods.
Spectrum analyzers
Spectrum analyzers are used to measure the power of an optical spectrum over a specified wavelength (frequency) span.
Thermal characterization of components
Services and tools to test the thermal characteristics of photonic components
Die bonding and pick-and-place assembly
Bonding of dies and chips on both planar and flexible substrates (excluding sub-micron flip-chip)
Fiber alignment and pigtailing
Fiber-waveguide alignment and permanent fiber pigtailing for photonic chips and modules
Flip-chip bonding with sub-micrometer accuracy
Most demanding flip-integration with sub-micron accuracy is needed for e.g. waveguide-waveguide coupling
