Absolute Position Total Internal Reflection Microscopy with an Optical Tweezer
Lulu Liu, Alexander Woolf, Alejandro W. Rodriguez +1
A non-invasive, in-situ calibration method for Total Internal Reflection Microscopy (TIRM) based on optical tweezing is presented which greatly expands the capabilities of this tec…
Distinctive Signature of Indium Gallium Nitride Quantum Dot Lasing in Microdisks Cavities
Alexander Woolf, Tim Puchtler, Igor Aharonovich +5
Low threshold lasers realized within compact, high quality optical cavities enable a variety of nanophotonics applications. Gallium nitride (GaN) materials containing indium galliu…
Geometry-induced Casimir suspension of oblate bodies in fluids
Alejandro W. Rodriguez, M. T. Homer Reid, Francesco Intravaia +4
We predict that a low-permittivity oblate body (disk-shaped object) above a thin metal substrate (plate with a hole) immersed in a fluidof intermediate permittivity will experience…
Low threshold, room-temperature microdisk lasers in the blue spectral range
Igor Aharonovich, Alexander Woolf, Kasey J. Russell +4
InGaN-based active layers within microcavity resonators offer the potential of low threshold lasers in the blue spectral range. Here we demonstrate optically pumped, room temperatu…
A full free spectral range tuning of p-i-n doped Gallium Nitride microdisk cavity
Nan Niu, Tsung-Li Liu, Igor Aharonovich +7
Effective, permanent tuning of the whispering gallery modes (WGMs) of p-i-n doped GaN microdisk cavity with embedded InGaN quantum dots over one free spectral range is successfully…
Controlled tuning of whispering gallery modes of GaN/InGaN microdisk cavities
Igor Aharonovich, Nan Niu, Fabian Rol +6
Controlled tuning of the whispering gallery modes of GaN/InGaN μ-disk cavities is demonstrated. The whispering gallery mode (WGM) tuning is achieved at room temperature by immersin…
