A high side modes suppression dual-loop optoelectronic oscillator with Fabry-Perot etalon

An Optoelectronic Oscillator Using A High Finesse Etalon

Tunable spatial filtering with a Fabry-Perot etalon.

A Fabry-Perot etalon is used in the image plane as a means of selecting arbitrary directions of propagation in the angular spectrum of an object. This provides a simple widely tunable spatial filter that could be useful in a number of image processing and pattern recognition applications.

Fabry Perot etalon with polymer cholesteric liquid-crystal mirrors.

We present what we believe to be the first implementation of a Fabry-Perot (FP) etalon using polymer cholesteric liquid-crystal mirrors. These polymer mirrors have each been fabricated onto a single substrate, which allows the FP cavity spacing to be only a few micrometers wide. For the experimental results presented, cavity lengths of 13.8 and 7.6 microm yield near-infrared free spectral range...

Very-high-resolution tandem Fabry-Perot etalon cylindrical beam volume hologram spectrometer for diffuse source spectroscopy.

We demonstrate a compact and slitless spectrometer with high resolution formed by cascading a Fabry-Perot etalon (FPE) and a cylindrical beam volume hologram (CBVH). The most significant advantage of this combined spectrometer is that we can independently encode spectral information of a diffuse beam in a 2D plane. Also, we show that in this slitless configuration we can simultaneously benefit ...

All optical, high contrast absorptive modulation in an asymmetric Fabry--Perot etalon

In recent years there has been a lot of interest in the development of optical processing elements for optical computing and neural networks. These devices are expected to exploit the high parallelism possible with optical systems. Several candidates have been proposed and demonstrated but it is still not clear which, if any, will be the clear leader in providing a cheap, reliable optical switc...
