Optical antenna enhanced spontaneous emission
TL;DR: In these experiments, InGaAsP nanorods emitting at ∼200 THz optical frequency show a spontaneous emission intensity enhancement of 35× corresponding to a spontaneously emission rate speedup ∼115×, for antenna gap spacing, d = 40 nm, proportional to 1/d2.
Journal ArticleDOI
Ultrafast Spontaneous Emission from a Slot-Antenna Coupled WSe2 Monolayer
Michael S. Eggleston,Sujay B. Desai,Sujay B. Desai,Kevin Messer,Seth A. Fortuna,Surabhi R. Madhvapathy,Surabhi R. Madhvapathy,Jun Xiao,Xiang Zhang,Xiang Zhang,Eli Yablonovitch,Ali Javey,Ali Javey,Ming C. Wu +13 more
TL;DR: In this article, the spontaneous emission rate of a monolayer transition metal dichalcogenides (WSe2) was estimated with a cavity-backed optical slot antenna through self-aligned fabrication process.
Proceedings ArticleDOI
Large spontaneous emission rate enhancement from an electrically-injected nanoLED coupled to an optical antenna
TL;DR: In this paper, an electrically-injected nanoLED coupled to a cavity-backed optical slot antenna was used to achieve a spontaneous emission rate on par with the stimulated emission rate.
Proceedings ArticleDOI
Electrically injected nanoLED with enhanced spontaneous emission from a cavity backed optical slot antenna
TL;DR: In this article, an electrically injected nanoLED with a cavity backed optical slot antenna was used to enhance the spontaneous emission rate. But the experimental results showed only 2x higher intensity of light emission with polarization parallel with antenna mode indicating the presence of spontaneous emission enhancement.
Proceedings ArticleDOI

TL;DR: In this article, a self-aligned process is developed to couple monolayer WSe 2 (30nm × 300nm) to a silver cavity-backed slot-antenna optical emission measurements show 340x enhancement in spontaneous emission Carrier lifetimes of <1ps are measured by streak camera
