Fewer components and optical elements required allows reduction in product size and new design options Lower power consumption Improved projection quality
About
About Researchers at the University of Glasgow have developed a technology which allows the manufacture of semiconductor lasers and associated devices with on chip polarisation control. This monolithically integrated component can be controlled to produce any output polarisation state from any input state where the resulting output polarisation state can be switched electronically to any other state on the nanosecond timescale. The research has previously demonstrated each of the constituent elements of the device and fully functional prototypes have recently been demonstrated. In principle this technology can be used at any wavelength where a semiconductor source exists, i.e. from the visible to the far infrared. Current display systems based on passive 3D technology have an additional polarisation modulation element in the optical path to produce two images required for the right and left eye. This integrated polarisation control technology will offer improvements in 3D laser projector systems due to the removal of this component and the additional capability of being able to switch polarisation of the laser source at high speed. Polarisation control and manipulation are key functions in optical communications. This technology will allow the production of equipment with significant cost savings by lifting design constraints due to the necessity of polarisation independence. For polarisation multiplexed and coherent detection based long-haul systems a waveguide based polarisation control technology capable of integration with current designs will become a key enabling technology. Key Benefits Benefits for 3D applications: Fewer components and optical elements required allows reduction in product size and new design options Reduced bill of materials (BOM) and hence cost of manufacture Improved projection quality Polarisation crosstalk removal Lower power consumption Applications 3D Applications Optical Communications IP Status This technology is available as an Easy Access deal, available to companies and individuals to licence for FREE.
