Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...

A sensing method based on resonance localized surface plasmon spectroscopy was developed for low molecular weight substrate and inhibitor molecules binding to heme proteins. Cytochrome P450 proteins have Soret and Q absorption bands in the visible wavelength region. The coupling between the molecular resonance of P450 and the localized surface plasmon resonance (LSPR) of functionalized silver n...

We utilize a low-cost, robust method of wavelength locking microring resonators to implement a simplified platform for microring-sensing applications that requires only a singlewavelength laser source and directly maps resonance shifts to DC voltage values. OCIS codes: (280.4788) Optical sensing and sensors; (280.1415) Biological sensing and sensors. With their small footprint, CMOS-compatible ...

We have developed a wideband tunable optical filter that uses a long-period fiber grating (LPFG) in which both resonance wavelength and its signal attenuation can be adjusted. We create the grating mechanically by pressing a spring coil to an optical fiber. We achieve continuous fine tuning of wavelength and attenuation by varying the temperature of the LPFG. The adjustable ranges of the LPFG a...

We present an automated setup to measure the surface plasmon resonance ~SPR!-enhanced optical absorption spectra of molecular adsorbates. The setup detects the reflectivity at the SPR resonance angle as a function of the incident light wavelength. Because the resonance angle is wavelength dependent, a feedback mechanism adjusts the photodetector position to follow the resonance angle when the w...
