INTRINSIC AND PHOTON-INDUCED DEFECTS ASSOCIATED WITH Ge IN OPTICAL FIBER
نویسندگان
چکیده
Structural models for darningand radiation-induced defects associated with Ge were confirmed to be E' type and spherical tetrahedron from the spin density on Ge, 30% and 35%, respectively, estimated from hfs due to 73~e. From the observation of thermal relaxation of radiation-induced center to Ge-E', the loss-increase due to OH formed on the reaction of a fiber with hydrogen molecule diffused from atmosphere was explained as the El-catalyzed formation of OH groups.

Optical Fiber Birefringence Effects – Sources, Utilization and Methods of Suppression
The application area of optical fibers is quite extensive. Telecommunication applications were the primary field of fibers employment. The related area is the utilization of optical fibers for control purposes, which benefits from principal galvanic isolation between the transmitting and receiving part of the system. A minimal sensitivity of light propagation inside the fiber to electromagnetic...
متن کاملNoise characterization of broadband fiber Cherenkov radiation as a visible-wavelength source for optical coherence tomography and two-photon fluorescence microscopy.
Optical sources in the visible region immediately adjacent to the near-infrared biological optical window are preferred in imaging techniques such as spectroscopic optical coherence tomography of endogenous absorptive molecules and two-photon fluorescence microscopy of intrinsic fluorophores. However, existing sources based on fiber supercontinuum generation are known to have high relative inte...

We are developing a hand-held imaging probe intended for intra-operative use. This probe is to be used after the bulk of a tumor has been removed. It will locate residual malignant tissue labeled by a pre-operative injection of a tumor-seeking radiopharmaceutical. The device presented here is a prototype system that consists of a 4 x 8 array of 925pm diameter plastic scintillating fibers. The i...

The future International Thermonuclear Experimental Reactor (ITER) is a complex installation that will require permanent monitoring and frequent maintenance operations. The high-gamma dose rates, the high neutron fluence and other radiological hazards call for the use of remotehandled equipment. The management of heavy umbilicals connecting the control systems with the remote tools is therefore...
متن کاملRadio-over-fiber transmission from an optically injected semiconductor laser in period-one state
Nonlinear dynamics of semiconductor lasers has found many interesting applications in microwave photonics technology. In particular, a semiconductor laser under optical injection of proper strength and optical frequency detuning can enter into the dynamical period-one (P1) state through Hopf bifurcation. The resulting optical output carries a broadly tunable high-speed microwave modulation with...
