A semiconductor structure with active zones, such as light diodes or photodiodes, including a substrate (SUB) with at least two active zones (AZ1-AZn), each of which emits or absorbs a radiation of differing wavelength. According to the invention, a multi-wavelength diode may be achieved, in which a...http://www.google.se/patents/US7692202?utm_source=gb-gplus-sharePatent US7692202 - Semiconductor structure comprising active zones
