An arrayed nanoantenna for broadband light emission and detection
optical nanoantennas subwavelength light guiding field enhancement unidirectional emission
2011/8/4
Abstract: We suggest a broadband optical unidirectional arrayed nanoantenna consisting of equally spaced nanorods of gradually varying length. Each nanorod can be driven by near-field quantum emitters...
Chaos-assisted directional light emission from microcavity lasers
light emission microcavity lasers

We study the effect of dynamical tunneling on emission from ray-chaotic microcavities by introducing a suitably designed deformed disk cavity. We focus on its high quality factor modes strongly locali...
Light Emission From Travelling Space Charge Domains
Light Emission Travelling Space Charge Domains

We report light emission from n-doped GaAs epilayers associated with impact ionization when the device is biased in the negative difference resistance (NDR) regime (F > 3.5 kV cm-1). Spectral distribu...
