Photonic crystals are ultra-compact highly integrated nano scale structures which demonstrated the possibility of generating, manipulating, processing, transmitting and detecting light. However, most photonic crystal devices are “passive” structures without any means of external on-demand control. Adding tunability to the photonic crystals would greatly expand their application areas and enable unforeseen new application areas. MEMS/NEMS technologies are ideally positioned to provide a wide variety of unprecedented radical options of tunability to the passive photonic crystal devices as they can be co-integrated with photonic crystals. We have recently reported MEMS-enabled mechanically tunable and thermally tunable photonic crystals. Various applications and current status of development of such tunable photonic crystals will be discussed.
