To optical packaging cost and enhance alignment accuracy, a new application strategy of Diffractive Optical Element (DOE) had been proposed to develop a new technology that can integrate DOE and Resonant Cavity LED (RCLED) in semiconductor manufacture processing. The passivation layer SiO<inf>2</inf> used to fabricate the integrated DOE of Dammann Grating.(More)
In this paper, a novel fiber-optic sensing system based on fiber Bragg gratings (FBGs) to measure foot plantar pressure is proposed. This study first explores the Pedar-X insole foot pressure types of the adult-size chart and then defines six measurement areas to effectively identify four foot types: neutral foot, cavus foot, supinated foot and flat foot.(More)
In this paper, a new application strategy of diffractive optical elements (DOEs) has been proposed. The research combined vertical-cavity surface emitting laser (VCSEL) with diffractive optical elements into a single opto-electric semiconductor device. In order to fabricate DOE-VCSEL, DOE surface profile can be integrated upon P-DBR layer of VCSEL structure(More)
