Direct bandgap group IV materials have been long sought for in both academia and industry for the implementation of photonic devices. This proposal works on the fundamental issues and planar photonic devices that are suitable for the integration with the group IV based electronic devices. In this project, we have accomplished a direct bandgap group IV materials of GeSn, b GeSn-based planar light emitting diode operated at near infrared with direct emission, and c the first planar photodetector Appl. Phys. Lett. 105, 231109 2014and references within This move a step forward toward the monolithic integration of optic and electronic devices in a single chip all group IV materials. Still, there are two other components waveguide channel and modulator that is needed for the all group IV materials optoelectronic and this will be the main targets for next project.
