The fabrication, characterization, packaging and commercialization of optoelectronically integrated lasers and modulators are proposed. These sources are important for a wide range of applications including wavelength division multiplexed (WDM) optical fiber transmission, all optical networks, free space communication, and, sensing systems. A multisection tunable single wavelength laser with curved waveguide would be designed , fabricated and integrated with an electroabsorption modulator. We propose (i) to carry out a systematic analysis and experimental demonstration of selective area growth process for various device integration schemes ; to design and develop tunable lasers in Phase I ; to design and fabricate integrated electroabsorption modulator and tunable laser device in Phase I, ; (ii) to carry out further design and development, packaging and commercialization of these devices in Phase II. Tunable laser technology has a wide range of applications including telecommunication systems, RF photonics systems, cable TV systems and sensor systems. These systems would benefit significantly if tunable lasers and integrated tunable laser and electroabsorption modulator with low cost are commercially available.
