Abstract: A method of testing a photonic device includes providing a plurality of optical test signals at respective inputs of a first plurality of inputs of an optical input circuit located on a substrate, combining the plurality of optical test signals into a combined optical test signal at an output of the optical input circuit, transmitting the combined optical test signal through the output to an input waveguide of an optical device under test, the optical device under test being located on the substrate, and measuring a response of the optical device under test to the combined optical test signal. Each of the plurality of optical test signals comprises a respective dominant wavelength of a plurality of dominant wavelengths.

Abstract: A process for the depolymerization and supersulfation of heparin and the so obtained supersulfated heparins are disclosed. The process comprises treating heparin with oleum containing from 2 to 6% free sulfuric anhydride at a temperature from -10.degree. to +20.degree. C. The obtained heparins have molecular weights from 2000 to 5000 and a sulfation degree from 3.4 to 4.3. All of them are endowed with a remarkable antithrombotic activity.
