Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. Rakić, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…
1D photonic crystal direct bandgap GeSn-on-insulator laser
Hyo-Jun Joo, Youngmin Kim, Daniel Burt +12
GeSn alloys have been regarded as a potential lasing material for a complementary metal-oxide-semiconductor (CMOS)-compatible light source. Despite their remarkable progress, all G…
Enhanced GeSn Microdisk Lasers Directly Released on Si
Youngmin Kim, Simone Assali, Daniel Burt +6
GeSn alloys are promising candidates for complementary metal-oxide-semiconductor (CMOS)-compatible, tunable lasers. Relaxation of residual compressive strain in epitaxial GeSn has…
Lasing in Group-IV materials
V. Reboud, D. Buca, H. Sigg +6
Silicon photonics in the near-Infra-Red, up to 1.6 um, is already one of key technologies in optical data communications, particularly short-range. It is also being prospected for…
Ultra-low threshold cw and pulsed lasing in tensile strained GeSn alloys
A. Elbaz, D. Buca, N. Von den Driesch +15
GeSn alloys are the most promising semiconductors for light emitters entirely based on group IV elements. Alloys containing more than 8 at.% Sn have fundamental direct band-gaps, s…
Density matrix theory of transport and gain in quantum cascade lasers in a magnetic field
Ivana Savic, Nenad Vukmirovic, Zoran Ikonic +4
A density matrix theory of electron transport and optical gain in quantum cascade lasers in an external magnetic field is formulated. Starting from the general quantum kinetic trea…
