Modulation of the two-photon absorption by electric fields in HgCdTe photodiode
H. Y. Cui, Z. F. Li, Z. L. Liu, C. Wang, X. S. Chen et al.
We demonstrate the tunability of the two-photon absorption (TPA) coefficient by adjusting the electric field in a HgCdTe (MCT) photodiode with cutoff wavelength of 5.2 [mu]m. The TPA coefficient was measured by using a picosecond pulsed laser with wavelength of 7.92 [mu]m. An enhancement of the TP ... [Appl. Phys. Lett. 92, 021128 (2008)] published Fri Jan 18, 2008.
