Novel vertical-cavity surface-emitting lasers withintegrated optical beam router

Abstract
A novel vertical-cavity surface-emitting laser (VCSEL) with integrated optical beam router is reported. The output beam of the VCSEL has been steered by as much as 9.6° away from the surface-normal direction. Integration of the beam routers with VCSELs significantly reduces the complexity and size of the switching nodes. This device is useful for ultra-dense optical interconnects in massively parallel computers.
