Light emitter devices, such as light emitting diode (LED) devices and related methods are disclosed. A light emitter device includes a ceramic based substrate, at least one LED chip disposed on the substrate, and a filling material. The ceramic substrate can include one or more surface features. The filling material can be disposed over and/or within a portion of the one or more surface features. Surface features can include one or more pedestals, trenches, holes, indentions, depressions, waves, and/or convexly or concavely curved surfaces. Surface features can improve optics of the LED device, for example, improving brightness, reflection, and/or light extraction associated with the device. Related methods are disclosed.
