The LD operates in both the ground and excited states and the gratings give a dual-mode separation around each emission peak of 5 nm, which is suitable as a continuous wave (CW) optical pump signal for a terahertz (THz) photomixer device. The setup also generates dual modes around both 1180 m and 1260 nm simultaneously, giving four simultaneous narrow linewidth modes comprising two simultaneous difference frequency pump signals. date: 2011-10-24 official_url: http://dx.doi.org/10.1063/1.3654154 vfaculties: VENG oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_source: crossref elements_id: 1018272 doi: 10.1063/1.3654154 lyricists_name: Nikitichev, Daniil lyricists_id: DNIKI05 full_text_status: public publication: Applied Physics Letters volume: 99 number: 17 article_number: 171107 issn: 0003-6951 citation: Leyman, R; Nikitichev, DI; Bazieva, N; Rafailov, EU; (2011) Multimodal spectral control of a quantum-dot diode laser for THz difference frequency generation.
