1. A device comprising:
a photonic integrated circuit configured to transmit light of a first color;
a pair of spaced-apart reflectors;
a color conversion layer, located within an optical cavity defined by the pair of spaced-apart reflectors, configured to:
receive the light of the first color from the photonic integrated circuit; and
convert at least a portion of the light of the first color into light of a second color that is different from the first color; and
a display configured to be illuminated by the light of the first color and the light of the second color.
