Efficient ultra-broadband low-resolution astrophotonic spectrographs
Pradip Gatkine, Greg Sercel, Nemanja Jovanovic +9
Broadband low-resolution near-infrared spectrographs in a compact form are crucial for ground- and space-based astronomy and other fields of sensing. Astronomical spectroscopy pose…
2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Monolithically integrated circuits for Optical injection locking of ring lasers with QKD and QPSK applications
Damiano Massella, Michael Wallace, Ronald Broeke +1
Optical injection locking of integrated ring lasers promises to be a key technology of the future, but it is still lacking experimental verification. In this paper we present two m…
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…
3-beam self-calibrated Kernel nulling photonic interferometer
Nick Cvetojevic, Frantz Martinache, Peter Chingaipe +6
The use of interferometric nulling for the direct characterization of extrasolar planets is an exciting prospect, but one that faces many practical challenges when deployed on tele…
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…
