Journal ArticleDOI
Plasmonic enhanced quantum well infrared photodetector with high detectivity
TL;DR: In this paper, a normal-incident quantum well infrared photodetector (QWIP) strongly coupled with surface plasmon modes was reported, and a periodic hole array perforated in gold film was integrated with In0.53Ga0.47As/InP QWIP to convert normal-instrained electromagnetic waves into surface Plasmon waves, and to excite the intersubband transition of carriers in the quantum wells.
Journal ArticleDOI
Opto-mechanical force mapping of deep subwavelength plasmonic modes.
John Kohoutek,Dibyendu Dey,Alireza Bonakdar,Ryan M. Gelfand,Alejandro Sklar,Omer Gokalp Memis,Hooman Mohseni +6 more
TL;DR: Maxwell's stress tensor method has been used to simulate the optical force and it agrees well with the experimental data, and could potentially produce field intensity and optical force mapping simultaneously with a high spatial resolution.
Journal ArticleDOI
Deep-UV microsphere projection lithography.
Alireza Bonakdar,Mohsen Rezaei,Robert L. Brown,Vala Fathipour,Eric Dexheimer,Sung Jun Jang,Hooman Mohseni +6 more
TL;DR: This Letter presents a single-exposure deep-UV projection lithography at 254-nm wavelength that produces nanopatterns in a scalable area with a feature size of 80 nm and characterize the lithography performance in terms of the proximity effect, lens aberration, and interference effect due to refractive index mismatch between photoresist and substrate.
Journal ArticleDOI
Impact of optical antennas on active optoelectronic devices.
Alireza Bonakdar,Hooman Mohseni +1 more
TL;DR: The fundamental reasons for and experimental evidence of the dramatic improvements that can be achieved by enhancing the light-matter interaction via an optical antenna in both photon-emitting and -detecting devices are described.
Journal ArticleDOI
Quantum-cascade laser integrated with a metal–dielectric–metal-based plasmonic antenna
TL;DR: A novel metal-dielectric-metal coupled-nanorods antenna integrated on the facet of a quantum-cascade laser is reported, which has potential applications in building mid-IR biosensors.
