  Here, we present an astrophotonic spectrograph in the near-IR H-band (1.45
-1.65 $\mu m$) and a spectral resolution ($\lambda/\delta\lambda$) of 1500. The
main dispersing element of the spectrograph is a photonic chip based on
Arrayed-Waveguide-Grating technology. The 1D spectrum produced on the focal
plane of the AWG contains overlapping spectral orders, each spanning a 10 nm
band in wavelength. These spectral orders are cross-dispersed in the
perpendicular direction using a cross-dispersion setup which consists of
collimating lenses and a prism and the 2D spectrum is thus imaged onto a
near-IR detector. Here, as a proof of concept, we use a few-mode photonic
lantern to capture the light and feed the emanating single-mode outputs to the
AWG chip for dispersion. The total size of the setup is 50$\times$30$\times$20
cm$^3$, nearly the size of a shoebox. This spectrograph will pave the way for
future miniaturized integrated photonic spectrographs on large telescopes,
particularly for building future photonic multi-object spectrographs.
