Presented is a dual wavelength structure wherein two edge-emitting devices are bonded with p-regions adjacent. The bonding medium is a conductive compound that forms a common electrode between the devices. Each device is separately addressable. Efficient coupling of emitted light into a single fiber...http://www.google.fr/patents/US4605942?utm_source=gb-gplus-shareBrevet US4605942 - Multiple wavelength light emitting devices
