We report measurements of the infrared optical response of thin black phosphorus under field-effect modulation. We interpret the observed spectral changes as a combination of an ambipolar Burstein-Moss (BM) shift of the absorption edge due to band-filling under gate control, and a quantum confined Franz-Keldysh (QCFK) effect, phenomena that have been proposed theoretically to occur for black phosphorus under an applied electric field. Distinct optical responses are observed depending on the… 
Anisotropic Quantum Well Electro-Optics in Few-Layer Black Phosphorus.
TLDR
This Letter reports an experimental investigation of three different, anisotropic electro-optic mechanisms that allow electrical control of the complex refractive index in few-layer black phosphorus from the mid-infrared to the visible: Pauli-blocking of intersubband optical transitions; the quantum-confined Stark effect; and the modification of quantum well selection rules by a symmetry-breaking, applied electric field.

TLDR
The measurements of the lower-energy infrared anisotropic optical response of thin b-AsP under different electrical gating reveal that in addition to band edge absorption, amplitude modulation of sub-band absorption up to ten percent is also obtained in reflection extinction.
