Noise in refractive index enhancement
نویسندگان
چکیده
By utilizing the interference between an absorptive resonance and an amplifying resonance, one can achieve an enhanced refractive index without an increase in absorption to the beam. We analyze noise added to the beam due to spontaneous emission while propagating through such an index enhanced medium. We find that, for a medium with a refractive index of n and of length L, n−1 2 / 0 L noise photons are added to the beam.

Microstrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials
Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...

متن کاملEffect of saturable response to two-photon absorption on the readout signal level of three-dimensional bit optical data storage in a photochromic polymer
We observe a saturable change in the refractive index induced by two-photon absorption in a photochromic polymer, while the erasable nature of the polymer is maintained. As a result, the support region of spatial frequencies of the recorded data bits caused by the refractive index change in the polymer is enlarged. This feature leads to the significant enhancement of the signal level in a refle...

A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...
متن کاملHigh-efficiency single molecule fluorescence detection and correlation spectroscopy with dielectric microspheres
Microspheres made of high refractive index melamine resin are shown to enhance the fluorescence from single molecules in solution by seven-fold, and simultaneously reduce the observation volume by thirteen-fold, as compared to state-of-the-art confocal microscopy. This fluorescence enhancement is demonstrated to dramatically increase the signal-to-noise ratio in fluorescence correlation spectro...
