Development of an integrated near-IR astrophotonic spectrograph

Pradip Gatkine, Meghna Sitaram, Sylvain Veilleux +2

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 i…
