Abstract
Devices and techniques are disclosed herein which include a die including side surfaces such that light emitted from the die can exit through the side surfaces. The die includes a first surface and a second surface opposite the first surface such that the distance between the first surface and the second surface is at least 100 micro meters. The die also include a wavelength converting material deposited external to the die such that the wavelength converting material covers the side surfaces. The wavelength converting material includes phosphor particles, a transparent risen carrier, and transparent particles configured to increase the volume of the wavelength converting material, the transparent particles having a refractive index (RI) that is similar to the RI of the transparent risen carrier.
