Development of near-infrared electrically pumped bismide-based laser technology
The aim of the doctoral thesis is to develop advanced up to milliwatt power electrically pumped laser diode (LD) technology for 1000-1300 nm applications in optical communication, quantum technologies and medical systems. The developed technology will include a more advanced design of LDs emitting from the surface. The challenges of manufacturing such lasers are associated not only with the epitaxy of bismide multiple quantum wells, but also with the doping of mirrors (DBR) and lithography (together with laser and metallization structures). Similar industrial LDs used by FTMC colleagues in the development of an optical tomography set-up are not flexible in terms of wavelength and power. The doctoral thesis will aim to develop a technology for controllable LD parameters.
