More Information
Summary:The present invention provides an integrated optical device comprising two optical devices. One of the optical devices that comprise the integrated optical device may have undergone quantum well intermixing to provide a shift in the absorption edge of that device. The absorption edge may be shifted to a longer wavelength. In one embodiment the integrated optical device comprises a laser and a electro absorption modulator and in a further embodiment the integrated optical device comprises a laser and a detector.
