 ed membrane photonic devices are highly desirable for 3D integrated photon
 ics\, free space communications\, imaging\, sensing\, and ranging applicat
 ions. Over the years\, my group has been focusing on semiconductor membran
 e photonics\, flexible electronics and optoelectronics\, based on transfer
  printed nanoscale crystalline membrane materials and scalable heterogeneo
 us integration photonic crystal nanaophotonic platforms. In this talk\, I 
 will discuss some of the research progresses made in my group\, in the are
 a of photonic crystal Fano resonance photonics for lasers\, filters\, imag
 ers\, and sensors. Based on photonic crystal membrane reflectors\, a ultra
 -compact VCSELs were proposed and demonstrated based on heterogeneously in
 tegrated III-V quantum well structures with silicon photonic crystal membr
 ane reflectors\, for on-chip integration. Based on critical coupling conce
 pt\, close to perfect absorption was demonstrated in a graphene coupled ph
 otonic crystal cavities. Based on high quality factor filters from single 
 or coupled-bi-layer photonic crystal cavities\, high speed spatial light m
 odulators and high sensitivity optical sensors were also demonstrated.
