Noninvasive respiration movement sensor based on distributed Bragg reflector fiber laser with beat frequency interrogation
A distributed Bragg reflector fiber laser-based respiration movement monitoring system has been proposed and experimentally demonstrated. To fabricate the sensing element for respiration monitoring, a fixture that consists ...
Programmable multi-wavelength filter with Mach–Zehnder interferometer embedded in ethanol filled photonic crystal fiber
We experimentally demonstrated a free spectrum range (FSR) tunable comb filter based on a programmable thermo-controlled Mach–Zehnder interferometer. The device is constructed by sandwiching a length of ethanol-filled ...
Programmable wavelength-tunable second-order optical temporal differentiator based on a linearly chirped fiber Bragg grating and a digital thermal controller
We proposed and experimentally demonstrated an all-fiber structured wavelength-tunable second-order optical temporal differentiator based on a linearly chirped fiber Bragg grating and a digital-controlled thermal array. ...
