The explanation of the Stark effect in hydrogen, the splitting of the Balmer lines in an external electric field, was a major success of the old quantum theory of Bohr and Sommerfeld. Borrowing techniques from celestial mechanics, Epstein and Schwarzschild found frequencies for the Stark effect components of these lines that were in excellent agreement with Stark’s experimental data. Using Bohr...

A strong optical Stark effect has been observed in (6,5) semiconducting single-walled carbon nanotubes by femtosecond pump-probe spectroscopy. The response is characterized by an instantaneous blueshift of the excitonic resonance upon application of pump radiation at photon energy well below the band gap. The large Stark effect is attributed to the enhanced Coulomb interactions present in these...

A strong interaction of a semiconductor with a below-bandgap laser pulse causes a blue-shift of the bandgap transition energy, known as the optical Stark effect. The energy shift persists only during the pulse duration with an instantaneous response time. The optical Stark effect has practical relevance for applications, including quantum information processing and communication, and passively ...

The absorption and Stark effect spectra of the 1250 nm hand associated with the oxidized special pair (P+) in Rhodobacter sphaeroides reaction centers have been measured. The absorption spectrum in the 1000-1450 nm region is essentially identical whether P+ is generated by chemical oxidation or continuous illumination. The Stark effect on the 1250 nm band of P+ is relatively small compared to t...

The resonance frequency of an InAs quantum dot strongly coupled to a GaAs photonic-crystal cavity was electrically controlled via the quadratic quantum confined Stark effect. Stark shifts up to 0.3 meV were achieved using a lateral Schottky electrode that created a local depletion region at the location of the quantum dot. We report switching of a probe laser coherently coupled to the cavity up...

The effect of the electric field on an exciton confined in a pair of vertically coupled quantum dots is studied. We use a single-band approximation and a parabolic model potential. As a result of these idealizations, we obtain a numerically solvable model, which is used to describe the influence of the electron–hole interaction on the Stark effect for the lowestenergy photoluminescence lines. W...
