In the area of nano photonics, scientists for the first time succeeded in integrating a laser with an organic gain medium on a silicon photonic chip. This approach is of enormous potential for low-cost biosensors that might be used for near-patient diagnosis once and without any sterilization expenditure similar to today’s strips for measuring blood sugar.
This is the first time organic lasers were integrated on a single silicon photonic chip, Christian Koos, researcher of KIT’s Institute of Photonics and Quantum Electronics (IPQ) and Institute of Microstructure Technology (IMT), reports. “The main advantage of the lasers consists in the fact that production of large series is associated with low costs. In the long term, manufacture at a price of some cents per laser might be feasible.”
