  The selective spatial mode excitation of a bi-dimensional grating-coupled
micro-cavity called a Cavity Resonator Integrated Grating Filter (CRIGF) is
reported using an incident beam shaped to reproduce the theoretical emission
profiles of the device in one- and subsequently two-dimensions.In both cases,
the selective excitation of modes up to order 10 (per direction) is confirmed
by responses exhibiting one (respectively two) spectrally narrow-band
resonance(s) with a good extinction of the other modes, the latter being shown
to depend on the parity and order(s) of the involved modes. These results paves
the way towards the demonstration of multi-wavelength spatially-selective
reflectors or fibre-to-waveguide couplers. Also, subject to an appropriate
choice of the materials constituting the CRIGF, this work can be extended to
obtain mode-selectable laser emission or nonlinear frequency conversion.
