Green vcsels based on nitride semiconductors
WebThis paper describes the status and prospects of gallium nitride-based vertical-cavity surface-emitting lasers (VCSELs) with semiconductor-based distributed Bragg reflectors. These optoelectronic devices, which emit laser light from the violet to green region, are expected to be a superior light source for the next-generation of displays and ... WebMay 7, 2024 · (b) Schematics of green VCSELs with curved bottom mirror. The researchers combined their device with existing blue and red VCSELs to produce white light, claimed as a first such demonstration (Figure 1). The team comments: “This is the first example of a VCSEL-based full-color light source, which will have a great impact on the industry.”
