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…

Controlling petals using fringes: discontinuous wavefront sensing through sparse aperture interferometry at Subaru/SCExAO

Vincent Deo, Sébastien Vievard, Nick Cvetojevic +9

Low wind and petaling effects, caused by the discontinuous apertures of telescopes, are poorly corrected -- if at all -- by commonly used workhorse wavefront sensors (WFSs). Wavefr…

Statistical tests with multi-wavelength Kernel-phase analysis for the detection and characterization of planetary companions

Mamadou N'Diaye, David Mary, Frantz Martinache +4

Kernel phase is a method to interpret stellar point source images by considering their formation as the analytical result of an interferometric process. Using Fourier formalism, th…

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…
