  We present a proof of concept compact diffraction limited high-resolution
fiber-fed spectrograph by using a 2D multicore array input. This high
resolution spectrograph is fed by a 2D pseudo-slit, the Photonic TIGER, a
hexagonal array of near-diffraction limited single-mode cores. We study the
feasibility of this new platform related to the core array separation and
rotation with respect to the dispersion axis. A 7 core compact Photonic TIGER
fiber-fed spectrograph with a resolving power of around R~31000 and 8 nm
bandwidth in the IR centered on 1550 nm is demonstrated. We also describe
possible architectures based on this concept for building small scale compact
diffraction limited Integral Field Spectrographs (IFS).
