Abstract: A laser-activated remote phosphor (LARP) target with a first layer having a first index of refraction and a phosphor dispersed within the first layer. A second layer which has a second index of refraction different from the first index of refraction and adjoins the first layer at an interface. The first index of refraction is higher than the second index of refraction such that the interface is configured to at least partially reflect light emitted from the phosphor.

Abstract: A silicone-grafted core-shell particle is described wherein the silicone-grafted core-shell particle comprises a core of an inorganic particle and a shell of a grafted poly(dimethylsiloxane) polymer formed from a bi-terminated poly(dimethylsiloxane) having reactive groups at each terminal end. The silicone-grafted core-shell particles may be dispersed in a polysiloxane polymer matrix and employed as an LED encapsulant.

Abstract: A reflective laser activated remote phosphor (LARP) package comprising: a phosphor platelet oriented in a first plane defined by an x-y plane; a laser diode (LD) positioned to be offset along the x-axis from the phosphor platelet and above the first plane along a z-axis perpendicular to the x-y plane, the LD comprising: an output facet configured for emitting a laser beam (LB), the LB comprising: a slow axis oriented in a first direction along which the LB diverges at a first angle; and a fast axis oriented in a second direction along which the LB diverges at a second angle greater than the first angle; wherein the LD is oriented such that: the LB is bisected by the phosphor platelet such that the slow axis of the LB lies in an x-z plane and the fast axis of the LB is perpendicular to an x-z plane.
