Novel intercore-cladding lithium niobate thin film coated MOEMS fiber sensor/modulator
Author(s): Jamlson, Tracee L.; Konreich, Phillip; Yu, Chung
Abstract: A MOEMS fiber modulator/sensor is fabricated by depositing a lithium niobate sol-gel thin film between the core and cladding of a fiber preform. The preform is then drawn into 125-micron fibers. Such a MOEMS modulator design ...

Mid infrared LHS system packaging using flexible waveguides
Author(s): Yu, Chung
Abstract: As mid IR fiber optic systems are rapidly approaching a reality, so is the feasibility of fiber optic laser heterodyne systems. Laser heterodyne spectroscopy for high resolution monitoring of atmospheric gaseous pollutants ...
NASA Center: NASA (non Center Specific)
Publication Year: 1987
Added to NTRS: 2005-08-25
Accession Number: 88N10607; Document ID: 19880001225; Report Number: NAS 1.26:181192, NASA-CR-181192
Robust, Brillouin Active Embedded Fiber-Is-The-Sensor System in Smart Composite Structures
Author(s): Yu, Chung
Abstract: Extensive review of our proposed sensing scheme, based mainly on the forward Guided Acoustic Wave Brillouin Scattering (GAWBS) with backward stimulated Brillouin scattering (sBs) as an auxiliary scheme for system fault ...

Study of nonlinear optical sBs phenomena in mid IR fibers
Author(s): Yu, Chung; Fong, C. K.
Abstract: This is the first reported attempt at investigation of the sBs phenomena in mid IR fibers using externally fed or laser self generated low frequency and microwave frequency phonon waves as diagnostic probes of such ...

Investigation of stimulated Brillouin scattering switching in mid infrared fibers
Author(s): Yu, Chung; Fong, Chee Kiong
Abstract: Backward stimulated Brillouin scattering (SBS) has been experimentally studied in midinfrared transparent AgCl and KRS-5 fibers. In the present scheme, pump transmission through the fibers and acoustooptic radiative effects ...
