Sub-wavelength resolution of optical fields probed by single trapped ions: Interference, phase modulation, and which-way information
نویسنده
چکیده
Taking recent experiments as examples, we discuss the conditions for sub-wavelength probing of optical field structures by single trapped atoms. We calculate the achievable resolution, highlighting its connection to the fringe visibility in an interference experiment. We show that seemingly different physical pictures, such as spatial averaging, phase modulation, and which-way information, describe the situation equally and lead to identical results. The connection to Bohr’s moving slit experiment is pointed out.

In this paper first we try to analysis the behavior ofthe SOAs in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. After that by employing thismodel as inline amplifier for a DWDM optical system, we havesimulated the transmission of 10 channels with bit rate 10 Gb/sup to distance 3970 km with RZ-DPSK modulation ...
متن کاملOptical-tweezing-based linear-optics nanoscopy.
Previous works reported that linear optics could be used to observe sub-wavelength features with a conventional optical microscope. Yet, the ability to reach a sub-200 nm resolution with a visible light remains limited. We present a novel widely-applicable method, where particle trapping is employed to overcome this limit. The combination of the light scattered by the sample and by the trapped ...
متن کاملAdaptive on-chip control of nano-optical fields with optoplasmonic vortex nanogates
A major challenge for plasmonics as an enabling technology for quantum information processing is the realization of active spatio-temporal control of light on the nanoscale. The use of phase-shaped pulses or beams enforces specific requirements for on-chip integration and imposes strict design limitations. We introduce here an alternative approach, which is based on exploiting the strong sub-wa...
متن کاملOptical characterization of subwavelength-scale solid immersion lenses
We present the fabrication and optical characterization of nano-scale solid immersion lenses (nano-SILs) with sizes down to a subwavelength range. Submicron-scale cylinders fabricated by electron-beam lithography (EBL) are thermally reflowed to form a spherical shape. Subsequent soft lithography leads to nano-SILs on transparent substrates, i.e. glass, for optical characterization with visible ...
متن کاملA Two-mode Interference Measurement for Nanometer Accuracy Absolute Distance Ranging
We present a laser ranging system, under development, that uses a high frequency modulated beam to achieve sub-nm resolution by the combined use of interferometric and time-of-flight measurements. We first describe how the absolute distance is extracted from a two-mode interference signal. In particular we show that the signal, which presents both optical and synthetic wavelength scales, is ess...
