Nanometric voids as optical antennas for rewritable momentum-engineered photonics in silicon
Aleksei I. Noskov, Evan P. Garcia, Haiping Sun +2
Optical antennas are widely used to localize electromagnetic fields far below the diffraction limit, enabling enhanced light-matter interactions across nanophotonics. Yet the regim…
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…
Two-photon absorption in silicon using real density matrix approach
David Ziemkiewicz, David Knez, Evan P. Garcia +7
Two-photon absorption in indirect gap semiconductors is an frequently encountered, but not well-understood phenomenon. To address this, the Real Density Matrix Approach is applied…
Electronic Raman scattering in silicon glass
Sergey S. Kharintsev, Elina I. Battalova, Aleksey I. Noskov +3
The nature of enhanced photoemission in disordered and amorphous solids is an intriguing open question. A point in case is light emission in silicon, which occurs when the material…
Photon momentum enabled light absorption in bulk silicon
Sergey S. Kharintsev, Aleksey I. Noskov, Elina I. Battalova +6
Photons do not carry sufficient momentum to induce indirect optical transitions in semiconducting materials such as silicon, necessitating the assistance of lattice phonons to cons…
