2001-11-15 · Osram Opto Semiconductors Leads The Way With Blue Lasers. Thursday 15th Noveer 2001. Various layers are deposited onto the SiC (silicium carbide) base substrate using the organometallic vapor phase epitaxy (MOVPE). A key step on the way to reducing power was to lower the threshold current of the laser. It became evident that one efficient
