In this chapter we theoretically examine Photonic Crystals and Metamaterials coupled with gain and explain how incorporation of a gain material in such systems can be treated numerically with the Finite Difference Time Domain technique. We show how loss compensation is achieved in Metamaterials and we highlight several aspects of the transition to lasing in certain Photonic Crystals.
