In this paper, we present a tilted fiber Bragg gratings (TFBG) based surface Plasmon resonance (SPR) labelfree sensors with boronic acid derivative (ABA-PBA) as receptor molecule to detect glycoprotein with high sensitivity and selectivity. Tilted fiber Bragg gratings (TFBG) as a near infrared wavelengths detecting element can be able to excite a number of cladding modes whose properties can be detected...
A hydrostatic pressure insensitive fiber-optic hydrophone based on the integration of a dual polarization fiber grating laser and an elastic diaphragm is proposed and experimentally demonstrated. The diaphragm converts acoustic pressure into transversal force onto the fiber laser but shows no response to the hydrostatic pressure. Therefore, the beat frequency is sensitive to acoustic signal but insensitive...
Tight, integrated accelerometers are current interests in Micro-Opto-electro-Mechanical-Systems (MOEMS). An optical accelerometer based on a novel integrated optical resonator is proposed. The transmission spectra and the relation between the structure parameters and the device sensitivity are simulated. This ring resonator structure shows great potential to develop high sensitive accelerometers.
