Photon echo in germanium with shallow donors
نویسندگان
چکیده
A theoretical study was made of the conditions for observing photon echo effect in a germanium crystal doped with shallow donors. numerical calculation medium polarization excited by sequence two optical pulses at frequency close to impurity transition has been made. The excitation pulse parameters, such as duration, inhomogeneous broadening transitions and relaxation rate population coherence system on is considered. key aspect experimental implementation control temperature under photoexcitation, since strongly depends lattice. Keywords: germanium, donors, coherent effects, echo.

Electron Spin Coherence of Shallow Donors in Natural and Isotopically Enriched Germanium.
Germanium is a widely used material for electronic and optoelectronic devices and recently it has become an important material for spintronics and quantum computing applications. Donor spins in silicon have been shown to support very long coherence times (T_{2}) when the host material is isotopically enriched to remove any magnetic nuclei. Germanium also has nonmagnetic isotopes so it is expect...
متن کاملPhoton Echo Relaxation In
We have observed deeply modulated photon echoes from Pr 3 ÷ ions in LaF3 reflecting nuclear hyperfine interactions in both the ground 3H 4 and excited 3P o states. We infer splittings of 0.75 MHz and 1.13 MHz for the 3P 0 state, lnhomogeneous broadening of the terminal levels is found to lead to echo modulation damping. A surprising concentration dependence of the photon echo relaxation rate is...
متن کاملZeeman splitting of shallow donors in GaN
The Zeeman splitting of the donor spectra in cubic and hexagonal GaN is studied using an effective mass theory approach. Soft-core pseudopotentials were used to describe the chemical shift of the different substitutional dopants. The donor ground states calculated range from 29.5 to 33.7 meV, with typically 1 meV higher binding in the hexagonal phase. Carbon is found to produce the largest dono...
متن کاملPhoton-echo-based logical processing.
Word-by-word logical AND and OR operation with photon-echo processing is demonstrated for what is to our knowledge the first time. The photon-echo process can store sequences of optical data before processing. The present logical operations on 8- and 4-bit words are performed by using single-shot frequency-chirped photon echoes. Data rates of approximately 1 MHz, input energies of 1-10 nJ/bit, ...
متن کاملLight-shift-modulated photon-echo.
We show that the AC-Stark shift (light-shift) is a powerful and versatile tool to control the emission of a photon-echo in the context of optical storage. As a proof-of-principle, we demonstrate that the photon-echo efficiency can be fully modulated by applying light-shift control pulses in an erbium-doped solid. The control of the echo emission is attributed to the spatial gradient induced by ...
