Proceedings ArticleDOI
Giant nonlinear response from plasmonic metasurfaces coupled to intersubband transitions
Jongwon Lee,Christos Argyropoulos,Pai-Yen Chen,Mykhailo Tymchenko,Feng Lu,Frederic Demmerle,Gerhard Boehm,Markus C. Amann,Andrea Alù,Mikhail A. Belkin +9 more
TL;DR: In this paper, highly nonlinear metasurfaces based on coupling of electromagnetically-engineered plasmonic nanoresonators with quantum-engineering intersubband nonlinearities were reported.
Journal ArticleDOI
Broadly tunable terahertz generation in mid-infrared quantum cascade lasers
Karun Vijayraghavan,Yifan Jiang,Min Jang,Aiting Jiang,Karthik Choutagunta,Augustinas Vizbaras,Frederic Demmerle,Gerhard Boehm,Markus C. Amann,Mikhail A. Belkin +9 more
TL;DR: High terahertz-generation efficiency and relaxed phase-matching conditions offered by the Cherenkov scheme allowed us to demonstrate, for the first time, an external-cavity terAhertz quantum cascade laser source tunable between 1.70 and 5.25 THz.
Journal ArticleDOI
Terahertz sources based on Čerenkov difference-frequency generation in quantum cascade lasers
Karun Vijayraghavan,R. W. Adams,Augustinas Vizbaras,Min Jang,Christian Grasse,Gerhard Boehm,Markus C. Amann,Mikhail A. Belkin +7 more
TL;DR: In this article, the authors report room-temperature terahertz sources based on Cerenkov difference-frequency generation in dual-wavelength mid-infrared quantum cascade lasers with giant resonant optical nonlinearities originating from intersubband transitions.
Journal ArticleDOI
Novel cascaded injection-locked 1.55-μm VCSELs with 66 GHz modulation bandwidth
Xiaoxue Zhao,Devang Parekh,E.K. Lau,Hyuk-Kee Sung,Ming C. Wu,Werner Hofmann,Markus C. Amann,Connie J. Chang-Hasnain +7 more
TL;DR: A novel cascaded configuration of optically injection-locked (COIL) VCSELs is demonstrated, which enables a wide and tailorable direct modulation bandwidth and scaling capability of this technique to achieve tailorable modulation response.
Journal ArticleDOI
Energy-efficiency of optical network units with vertical-cavity surface-emitting lasers.
TL;DR: It is experimentally characterize and analytically show that the fast settling time and low power consumption during active and power-saving modes allow the VCSEL-ONU to achieve significant energy savings over the distributed feedback laser (DFB) based ONU.
