“…This material has attracted interest for applications in spatial-spectral holography [1][2][3][4] and quantum information science (QIS) [5][6][7][8][9][10][11] where other Tm 3 + materials have been widely employed. Rare-earth-doped LiNbO 3 also offers unique possibilities for integrating the well-established LiNbO 3 waveguide and nonlinear electro-optic technologies with the properties of the rare-earth ions.…”

a b s t r a c tWe report studies of decoherence and spectral hole burning for the 794 nm optical transition of thulium-doped lithium niobate. In addition to transient spectral holes due to the 3 H 4 and 3 F 4 excited states of Tm 3 + , persistent spectral holes with lifetimes of up to minutes were observed when a magnetic field of a few hundred Gauss was applied. The observed anti-hole structure identified the hole burning mechanism as population storage in the 169 Tm nuclear hyperfine levels. In addition, the magnetic field was effective in suppressing spectral diffusion, increasing the phase memory lifetime from 11 ms at zero field to 23 ms in a field of 320 Gauss applied along the crystal's c-axis. Coupling between Tm 3 + and the 7 Li and 93 Nb spins in the host lattice was also observed and a quadrupole shift of 22 kHz was measured for 7 Li at 1.7 K. A Stark shift of 18 kHz cm/V was measured for the optical transition with the electric field applied parallel to the c-axis.

“…interactions [1][2][3][4][5]. These properties have been exploited in a range of applications such as photonic signal processing at GHz and higher bandwidths [6][7][8][9][10][11] and laser frequency stabilization down to the Hz level or better [12][13][14]. Rare-earthdoped crystals are also one of the most promising systems for solid-state quantum memories, which are essential for longdistance quantum communications [15][16][17][18][19][20] and linear optics quantum computing [21,22].…”

“…With this motivation, we present a simple approach based on analysis of photon echo decay measurements for extracting underlying material properties that can be used to fully describe decoherence due to ISD. Following the detailed derivation of the basis for our method and comparison to other analysis approaches employed in previous work, we present specific examples of our approach for new ISD measurements on Tm 3+ :YAG, Tm 3+ :LiNbO 3 and Tm 3+ :YGG, three important thulium-doped crystals used in a number of ongoing signal processing and quantum information demonstrations [6][7][8][9][10][11][12][13][16][17][18][19]. Our results reveal that the new material system Tm 3+ :YGG has superior coherence properties compared to any previously studied thulium material.…”

A method is introduced for quantitatively analyzing photon echo decay measurements to characterize excitation-induced decoherence resulting from the phenomenon of instantaneous spectral diffusion. Detailed analysis is presented that allows fundamental material properties to be extracted that predict and describe excitation-induced decoherence for a broad range of measurements, applications and experimental conditions. Motivated by the need for a method that enables systematic studies of ultra-low decoherence systems and direct comparison of properties between optical materials, this approach employs simple techniques and analytical expressions that avoid the need for difficult to measure and often unknown material parameters or numerical simulations. This measurement and analysis approach is demonstrated for the 3 H 6 to 3 H 4 optical transition of three thulium-doped crystals, Tm 3+ :YAG, Tm 3+ :LiNbO 3 and Tm 3+ :YGG, that are currently employed in quantum information and classical signal processing demonstrations where minimizing decoherence is essential to achieve high efficiencies and large signal bandwidths. These new results reveal more than two orders of magnitude variation in sensitivity to excitation-induced decoherence among the materials studied and establish that the Tm 3+ :YGG system offers the longest optical coherence lifetimes and the lowest levels of excitation-induced decoherence yet observed for any known thulium-doped material.

“…(In 1994, it was also suggested and demonstrated that S2 materials could be used to create hyperspectral images of the sun [20]). Initially, it was thought that the readout time of a spectrum from an absorption profile was limited by the desired resolution bandwidth of the spectrum analyzer, limiting the chirp rate, κ, to (δω res ) 2 [25,27,28]. Readout faster than this rate causes distortion of the spectral hole, due to the Kramers-Kronig relation [20].…”

From spectral holeburning memory to spatial-spectral microwave signal processing

Many storage and processing systems based on spectral holeburning have been proposed that access the broad bandwidth and high dynamic range of spatial-spectral materials, but only recently have practical systems been developed that exceed the performance and functional capabilities of electronic devices. This paper reviews the history of the proposed applications of spectral holeburning and spatial-spectral materials, from frequency domain optical memory to microwave photonic signal processing systems. The recent results of a 20 GHz bandwidth high performance spectrum monitoring system with the additional capability of broadband direction finding demonstrates the potential for spatial-spectral systems to be the practical choice for solving demanding signal processing problems in the near future.
