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.
متن کاملFabry 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...
متن کاملThickness variation compensation in a Fabry–Perot modulator array using a self-tuned Fabry–Perot structure
A method is presented for compensating cavity thickness variations in conventional Fabry–Perot devices through the replacement of the input mirror with a holographic mirror, resulting in a self-tuned Fabry–Perot ~STFP! device. The technique is suitable for integrating large arrays of electro-optic Fabry–Perot modulators with silicon circuitry. Experimental results of a STFP modulator are presen...
متن کاملNovel method to stabilize a laser wavelength unaffected by Fabry-Perot etalon angle drift
Jow-Tsong Shy National Tsing Hua University Department of Physics Hsinchu 300, Taiwan Abstract. A laser with its wavelength stabilized to a Fabry-Perot etalon has many industrial applications. An ideal error signal for laser stabilization is the dispersion-like signal generated without wavelength modulation. We present a technique, by which the error signal is generated by the difference of two...
متن کاملTransmission characteristics of a Fabry-Perot etalon-microtoroid resonator coupled system.
The transmission spectra of a Fabry-Perot etalon coupled to a microtoroid resonator are studied theoretically and experimentally. The resonance line shapes depend strongly on the resonance wavelength detuning and coupling strength between the two resonators. A wide variety of line shapes, ranging from a single to triple peaks, symmetric to asymmetric Fano-like peaks, and notches were predicted ...
