New paper published in Optics Letters with a spectrally programmable waveplate
We published a new paper in Optics Letters entitled «Optical retarder system with programmable spectral retardance«. In this work we demonstrate an optical system that works as a retarder waveplate with programmable spectral retardance. The input light beam is spectrally dispersed and different spectral components are projected onto different pixels of a LCoS-SLM. Then, a different retardance is addressed for each pixel, adapted to the incoming wavelength. Light reflected recombined by the same setup. In this way a programmable polarization spectrum can be encoded.
This work was initiated as part of the final degree project of Jose Carrion, and has been done in collaboration with Prof. Juan Campos, from UAB group.
