Development of Optoelectronic Devices and Computational Tools for the Production and Manipulation of Heavy Rydberg Systems
… novel design is presented for a highly sensitive optical spectrum analyzer for displaying laser mode structure in real time. Utilizing programmable microcontrollers to read data from a CMOS image sensor illuminated by the diffraction pattern from a Fabry-Perot interferometer, this device can …

Bragg grating sensor interrogation using in-line, dual-mode fiber demodulators
Optical fiber Bragg gratings, first demonstrated by Hill in 1978 [1], will see increasing deployment as sensors in smart structure applications due to their minimal insertion loss and small profile. Bragg grating sensors provide narrowband reflections from a periodic index discontinuity. Strain and …

Devitrification Kinetics and Optical Stability of Optical Fibers at High Temperatures
Reliable sensing and monitoring systems based on optical fibers operating at high temperatures and in harsh environments are of high demand. One of the limitations of such systems is the devitrification of the fused silica based core and cladding glass at elevated temperatures. Crystallites can …

Composite Films for Modifying Evanescent Wave Characteristics in Long-Period Grating Biosensors
… mixtures and demonstrate a rapid response. Fiber optical immunosensors based on long-period gratings have limited sensitivity at the refractive index of ordinary aqueous solutions (~1.33). A composite film was designed to raise the local refractive index of the sensor, thus increasing sensitivity. …
