Flattening laser frequency comb spectra with a high dynamic range, broadband spectral shaper on-a-chip
Nemanja Jovanovic, Pradip Gatkine, Boqiang Shen +9
Spectral shaping is critical to many fields of science. In astronomy for example, the detection of exoplanets via the Doppler effect hinges on the ability to calibrate a high resol…
An all-photonic, dynamic device for flattening the spectrum of a laser frequency comb for precise calibration of radial velocity measurements
Nemanja Jovanovic, Pradip Gatkine, Boqiang Shen +9
Laser frequency combs are fast becoming critical to reaching the highest radial velocity precisions. One shortcoming is the highly variable brightness of the comb lines across the…
Simulating the Study of Exoplanets Using Photonic Spectrographs
Marcos Perez, Pradip Gatkine, Nemanja Jovanovic +3
Photonic spectrographs offer a highly miniaturized, flexible, and stable on-chip solution for astronomical spectroscopy and can be used for various science cases such as determinin…
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…
An on-chip astrophotonic spectrograph with a resolving power of 12,000
Pradip Gatkine, Nemanja Jovanovic, Jeffrey Jewell +2
With the upcoming extremely large telescopes (ELTs), the volume, mass, and cost of the associated spectrographs will scale with the telescope diameter. Astrophotonics offers a uniq…
Potential of commercial SiN MPW platforms for developing mid/high-resolution integrated photonic spectrographs for astronomy
Pradip Gatkine, Nemanja Jovanovic, Christopher Hopgood +6
Integrated photonic spectrographs offer an avenue to extreme miniaturization of astronomical instruments, which would greatly benefit extremely large telescopes and future space mi…
