B. Luo et al., DETERMINATION OF WAVELENGTH DEPENDENCE OF THE REFLECTIVITY AT AR COATED DIODE FACETS, IEEE photonics technology letters, 5(11), 1993, pp. 1279-1281
Wavelength dependence of the reflectivity at an AR coated diode facet
has been determined by comparing the spontaneous emission spectra obta
ined under the same bias condition before and after this facet is AR c
oated. Reliable measurements can be achieved by proper choice of the b
ias current.
