Video-rate mid-infrared imaging in the molecular fingerprint region via nanosecond non-degenerate two-photon absorption
Evan P. Garcia, Yryx Y. L. Palacios, Ryan Nguyen +4
Non-degenerate two-photon absorption (NTA) offers an attractive route for wide-field mid-infrared (MIR) imaging by mapping long wavelength information into the spectral detection w…
Broadband Photo- and Electroluminescence from Bulk Silicon via Strong Photonic Confinement
Aleksei I. Noskov, Alexander B. Kotlyar, Eric O. Potma +1
Silicon indirect bandgap fundamentally limits its ability to emit light, hindering the development of silicon-based light sources. Here, we explore a conceptually new solution to t…
Overcoming the indirect bandgap: efficient silicon emission via momentum-expanded photonic states
Aleksei I. Noskov, Alexander B. Kotlyar, Liat Katrivas +6
Silicon's inherently indirect bandgap severely limits its radiative efficiency, posing a fundamental challenge to the development of practical silicon-based light sources. While st…
