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 ) and a spectral resolution () of 1500. The main dispersing element of the spectrograph i…
Integrated Arbitrary Filter with Spiral Gratings: Design and Characterization
Yi-Wen Hu, Shengjie Xie, Jiahao Zhan +3
We report the design and characterization of a high performance integrated arbitrary filter from 1450 nm to 1640 nm. The filter's target spectrum is chosen to suppress the night-sk…
