Stellar photonics

The Plasma Acoustic Shield System, or PASS, is in the process of being developed by Stellar Photonics. In this work, we outline how extreme adaptive optics systems will enable advanced photonic and diffraction-limited technologies to be exploited in spectrograph design and the impact it will have on spectroscopy. We illustrate that the precision of an instrument based on these technologies, would be limited . With such Strehl ratios, efficient injection into single-mode fibers (SMFs) or photonic lanterns becomes possible.

Enhancing Stellar Spectroscopy with Extreme Adaptive Optics and Photonics.

Please join us in San Francisco for the SPIE Photonics West Exhibition next week: January – Feb 2nd.

We look forward to seeing you at BOOTH .

Tiphaine Lagadec Jon Lawrence Nemanja Jovanovic Olivier Guyon Michael J. The temporal behavior of stellar speckle patterns is statistically analyzed. The time-only power spectrum is shown to be the sum of two exponentially decreasing functions defining two characteristic time constants. The corresponding correlation is the sum of two Lorentzian functions.

This is consistent with the first-order . Photonic technologies hold immense promise to revolutionise astronomical instrumentation.

In stellar interferometry the fringe visibility can be measured by modulating the optical path difference between the two arms of an interferometer.

This approach yields accurate estimates of the fringe visibility only if the bandwidth is small, and this limits the sensitivity of the technique.
