Individually-controlled optical beams are incident upon single or grouped atomic systems, providing programmable control. a An example spectrogram of a waveform Ω1 consisting of a chirped pulse followed by a fast pulse incident on the channel labeled “1”. Large switching bandwidth Δω and, correspondingly, small switching time Δt are desired for flexible spectro-temporal control. b Numerous atomic systems—from solid state memories, to ions, to neutral atoms—have visible wavelength transitions near 780 nm, a regime inaccessible by active photonics developed in silicon or indium phosphide for telecommunications. We note a canonical example for each category, including especially the negatively-charged silicon-vacancy center in diamond which we use in “Application” to demonstrate the capabilities of our device.
