Photonics systems in the ultra-violet to visible spectral regime are based on wide-bandgap materials and devices. The development of III-Nitride photonic and optoelectronic devices integrated on a monolithic semiconductor platform will enable radical advances in a wide range of applications, including: smart lighting, sensing, imaging, visible-light communications, chip-scale atomic systems (including optical clocks), quantum photonics and quantum communications. In this talk, I’ll present the design, fabrication, and characterization of the monolithic integrated laser diodes together with modulators, amplifiers, and detectors towards wide-bandgap photonic integrated circuits. The challenges and opportunities in seamlessly integrated III-nitride elements enabling photonic IC at the visible wavelength for many critical applications will be discussed.
