1. A multiwavelength light emitting device comprising:
- two light emitting devices, each comprising a confined light emitting region which emits light at a different wavelength, said devices being bonded with a conductive material that forms a common electrode between them, the light emitting regions being sufficiently close together to couple light from both regions into a single optical fiber; and
means for electrically addressing each device separately.

Abstract
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 is accomplished by restricting the vertical and horizontal separation of the light emitting stripes.
