In this paper, we fabricated the polymer waveguide type surface plasmon resonance (SPR) sensor using a white light source and optical spectrum analyzer (OSA). Fabricated sensor uses the principle of phase matching between evanescent wave... CS Park,SH Yeom,DE Kim,... - 《Journal of the Kore...
Broadband sources, based on light emitting diode (LED) principle, have a power spectral distribution that covers a broad range of wavelengths, usually tens or hundreds of nanometers; hence, LED sources illuminate wide portions of the optical spectrum (e.g., the entire third optical window or ...

The function of the TLS is to probe the transmission at the wavelength of the most sensitive mode of the fiber grating (the SPR mode here), determined by initial calibration with a spectrum analyzer. This technique relies on the principle of edge filtering so that the optical power change is...
running the signal in a certain trigger frequency (TactivityinFig. 8a and 8b) and measuring the signal. In EOFM, a laser scans the region of interest (ROI) on the device under attack and feeds the detected signal from laser reflected signal into a spectrum analyzer acting as a narrow ...
One of the challenging tasks in FBG sensing is to determine the Bragg wavelength shift, which can be done by using an optical spectrum analyzer (OSA)... J Chicharo 被引量: 0发表: 0年 SERS sample vials based on sol-gel process for trace pesticide analysis Here the potential for developing...
For example, on-chip asymmetric propagation by phase-gradient metasurface has been accomplished over a broadband THz spectrum (Fig. 9f)178. Depending on the propagation direction and polarization, it decreases or guides light through waveguides. The principle behind this is based on the asymmetrically...
The spectrum of the optical signal was measured by the optical spectrum analyzer (OSA, Yokogawa AQ6730D). The resolution of the OSA is 0.02 nm, in which it is difficult to distinguish the RF and LO signals in optical spectra. When the ML is injected into the SL, the resonant state in...
Therefore, this review mainly begins with the principle of chiral optical fibers, introduces their preparation and latest application scenarios, and finally discusses their potential future development prospects. Keywords: chiral fibers; microstructured optical fibers; fiber devices ...
