High-speed modulation of a terahertz quantum cascade laser by coherent acoustic phonon pulses

High-speed modulation of a terahertz quantum cascade laser by coherent acoustic phonon pulses

The typical electronic modulation of terahertz quantum cascade lasers is fundamentally limited at fast timescales by device properties. Here the authors propose and study an alternative, acoustic mechanism for modulating such THz QCLs at high speed.
