In this communication, we report on the design, the fabrication and the near field optical microscopy of (i) a Negative Index Material (NIM) flat lens, (ii) a GRadient INdex (GRIN) slab and (iii) a two-dimensional cloaking device. They were all fabricated on the basis of a InP-based photonic crystal technological platform and show the possibility of subwavelength focusing by NIM or GRIN principles and wave reconstruction for a reflector cloak through transformational optics.
