Joint spectral characterization of SPDC photon pairs near 2 m in (Al)GaAs-on-insulator waveguides
Alexandre Z. Leger, Emil Z. Ulsig, Samuel E. Fontaine +8
Integrated photon-pair sources are a core component of chip-based quantum computing, communication, and metrology. Although such sources have been demonstrated at conventional tele…

Theory of the two-photon Franz-Keldysh effect and electric-field-induced bichromatic coherent control
J. K. Wahlstrand, J. E. Sipe
The effect of a constant electric field on two-photon absorption in a semiconductor is calculated using an independent-particle theory. The theoretical framework is an extension of…
