OPTICAL LABORATORY

The optical laboratoy has several experimental techniques for the analysis of the irradiated materials.

Prism-coupling for optical waveguide characterization:

With this technique the effective refractive index of the propagating modes of a wave guide is measured. From this measurement the in-depth refractive index profile of the waveguide is determined. Optical propagation losses can also be determined by using a CCD camera to measure and analyze the out-scattering light.

Optical reflectance and transmittance:

A home-made system is available built using a white light (UV-VIS range) and optical fibers to send the light at the samples which, optionally, can be heated at to 400 ºC in a plate-like furnace. There are two possible detectors: a compact spectrometer Ocean Q65000 (λ: 200-900 nm) and a high resolution espectrometer Andor-SR500i with and high sensitivity ANDOR Newton camera detector (λ: 200-1000 nm).

Raman spectroscopy is also available at 532 nm wavelength using the ANDOR Newton spectometer .

Ellipsometer Woolam M2000 (wavelength range: 200-1000 nm) for fast parallel multichannel measurements (integration time < 1s).

All these portable equipments can be used for in-situ optical measurement during ion irradiation.
