Next generation of InGaN lasers -- in search of new functionality and better integration

Presented by Prof. Piotr Perlin, Institute of High Pressure Physics, “Unipress”, Warsaw, Poland

Nitride semiconductor laser diodes have found their place in many optoelectronic technologies, including lighting techniques, image projection, and optical data storage. With the growing maturity of existing technologies, the time has come to develop devices that go beyond the standard Fabry-Perot laser diodes. During this presentation I will briefly discuss the development of superluminescent diodes and semiconductor optical amplifiers and distributed feedback (DFB) lasers operating in the visible spectral range. The last two devices are necessary for applications such as optical atomic clocks, but they can also be the basis for future integrated photonic integrated systems (PICs) and visible telecommunication including Li-Fi. I will also discuss the concept of high power two-dimensional laser arrays, which can be the key concept for image projection systems and power systems such as non-ferrous metal welders.
