Abstract

We demonstrate implementation of the chirp transform algorithm with photon echoes in an Er/sup 3+/:YSO crystal at 1536 nm for application to spectral analysis of RF signals. The principle and features of the technique are presented using a simple picture in the time-frequency plane. Experimental results with low-bandwidth RF signals demonstrate 40-kHz spectral resolution and a time-bandwidth product of 500. Extension to broad-band RF signals is discussed.

Wide Band&high resolution, RF spectral analysis using a high purity frequency agile laser oscillator

We report on the demonstration of the chirp transform algorithm for the optical processing of wide band RF signals. The process uses photon echoes in an Er3+:YSO crystal at 1536 nm. The analysis covers a 1.5 GHz instantaneous bandwidth together with more than 20,000 independent channels. These performances require a frequency agile laser source that is phase-locked in order to take advantage of the high coherence of the system

Time-to-frequency Fourier transformation with photon echoes

Loïc Ménager, J.-L. Le Gouët, I. Lorgeré

We propose to use photon echoes in rare-earth-doped crystals to implement the Fourier-transform chirp algorithm. The process is considered for application to spectral analysis of fast radio-frequency signals. Compared with surface acoustic wave devices, the proposed scheme gives access to the larger bandwidths of rare-earth-doped crystals and greater flexibility. An experimental demonstration of the proposed process is reported.

Wideband and high-resolution coherent optical transients with a frequency-agile laser oscillator

Vincent Crozatier, Guillaume Gorju, J.-L. Le Gouët +2 more

We report what is believed to be the first experimental demonstration of a wideband spectral coherent process driven by a frequency-agile laser in a rare-earth-ion-doped crystal. The very demanding chirp-transform algorithm is studied in detail and is applied to radio-frequency spectral analysis. A time-bandwidth product of 24,000 is demonstrated.

Spectral hole burning for wideband, high-resolution radio-frequency spectrum analysis

Friso Schlottau, Max Colice, Kelvin H. Wagner +1 more

We present experimental results for what is to our knowledge the first spectral-hole-burning based rf spectrum analyzer to cover 10 GHz of rf analysis bandwidth. The rf signal of interest is modulated onto an optical carrier, and the resultant optical sidebands are burned into the inhomogeneously broadened absorption band of a Tm3+:YAG crystal. At the same time a second, frequency-swept laser reads out the absorption profile, which is a double-sideband replica of the rf spectrum, and thus the rf spectrum can be deduced after spectral calibration of the nonlinear readout chirp. This initial demonstration shows spectral analysis covering 10 GHz of bandwidth with >5500 spectral channels and provides 43 dB of dynamic range.

10-GHz bandwidth RF spectral analyzer with MHz resolution based on spectral hole burning in Tm/sup 3+/:YAG

Guillaume Gorju, Vincent Crozatier, I. Lorgeré +2 more

We demonstrate the first 10-GHz instantaneous bandwidth radio-frequency spectrum analyzer based on spectral hole burning in Tm/sup 3+/:YAG. It exhibits 10 000 frequency channels and a resolution better than 1 MHz. Thanks to the fast and linear chirping capabilities of the laser used, it has a potential 100% probability of interception and a response time in the millisecond range. Its linear dynamic range of 16 dB is presently essentially limited by the modest amount of optical power available and can be further improved.
