Astronomers studying exoplanets are in need of new technical solutions to further their understanding of planetary formation processes and planetary types. Astrophotonics, which applies photonic technologies to observational astronomy, offers a promising avenue forward. This paper discusses various
To measure small velocity changes, a stable spectral calibration source called a laser frequency comb (LFC) is critical. LFC emits ultra-stable, uniformly spaced lines that can calibrate an instrument over many years. There are different ways to generate the
Detecting extraterrestrial life on a zone planet requires a large telescope and advanced high contrast imaging techniques. These techniques involve wavefront sensing and control to eliminate aberrations and improve contrast, as well as starlight suppression using a coronagraph. However,
Photonic lanterns can be used for nulling, suppressing starlight while allowing planet light to be coupled. A 6 port mode-selective lantern operating at 1550 nm has demonstrated monochromatic and polychromatic null depths ranging from
There are several possible architectures for a photonic-based instrument to detect and characterize Earth-like planets around sun-like stars. One approach is to use a coronagraph with moderately high contrast and then use photonic components downstream to enhance the contrast. One potential architecture
Technologies like LFCs are already at technology readiness level (TRL) 9 and are being widely used at ground-based observatories. Nulling and wavefront control technologies range from TRL 2-5 depending on the approach. There is
