Ø Abstract
  
Spatially reconfigurable Gaussian-shaped photonic well is generated by contacting
a curved  tapered  micro-fiber onto a photonic crystal waveguide.  We  confirm the
photon trapping in this relocatable well by observing lasing action slightly below the
corresponding band edge.  In addition,  the feasibility of sub-nanometer  resonant
Tuning  is  demonstrated  by  growing  electron-beam-induced  nano-dots  inside
high-Q photonic crystal resonators.
