Wide stripe single and dual wavelength mode semiconductor diode lasers
… with respect to emission wavelength, external gratings such as volume Bragg gratings have been used. These external gratings not only significantly drive up the cost of such integrated systems but also have their drawbacks in that they are very sensitive to mechanical vibrations. This work has …

Materials science and design for germanium monolithic light source on silicon
… we designed an external cavity Ge laser using distributed Bragg reflector (DBR) gratings on Si waveguides. A detailed discussion on the cross section design was presented to mitigate the internal optical loss from claddings and metal layers and to improve the current injection uniformity across …
