O. Hanaizumi et al., MEASUREMENT OF CARRIER-INDUCED CHANGES OF THE COMPLEX REFRACTIVE-INDEX IN INGAASP NEAR THE BAND-EDGE, Optics communications, 120(3-4), 1995, pp. 158-165
A new method has been developed to measure the complex refractive inde
x changes of a thin film medium, using a probe light perpendicularly t
ransversing the surface and a small interference-ellipsometry bridge.
Carrier-induced changes of the refractive index and absorption have be
en measured in InGaAsP near the band edge using this method. Experimen
tal results are compared with calculations.
