High-Temperature Sensor Based on Fabry-Perot Interferometer in Microfiber Tip [PDF]

open access: yesSensors, 2018
A miniaturized tip Fabry-Perot interferometer (tip-FPI) is proposed for high-temperature sensing. It is simply fabricated for the first time by splicing a short length of microfiber (MF) to the cleaved end of a standard single mode fiber (SMF) with ...

Single electron interference and capacitive edge mode coupling generates ϕ 0/2 flux periodicity in Fabry-Pérot interferometers [PDF]

open access: yesNature Communications
Experimental observations of flux periodicity ϕ 0/2, where ϕ 0 = h/e, for interference of the outermost edge mode in the integer quantum Hall regime have been attributed to an exotic electron pairing mechanism.
