An extremely sensitive and simple fiber loop-cavity ringdown spectroscopy (FL-CRDS) setup has been designed based on a turn-key nanosecond pulse laser source operating at 1535 nm. The system sensitivity is demonstrated to be approximately 0.01 dB after extracting the characteristic macrobend loss curve of a standard single mode fiber (SMF-28). The experiment demonstrated that the oscillatory behavior in the rapid loss due to the increasing curvature could be seen for single turn bare fibers with radii of curvature from 10-20 mm. Since the wavelength of laser lies in the range of the conventional window, known as C-band, the demonstrated scheme may suggest the use of these techniques in versatile applications where quick results are necessary without the system complexity.

A low-cost uncooled infrared microbolometer detector in standard CMOS technology
Tezcan, DS; Eminoglu, S; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2003-02-01)
This paper reports the development of a low-cost uncooled infrared microbolometer detector using a commercial 0.8 mum CMOS process, where the CMOS n-well layer is used as the infrared sensitive material. The n-well is suspended by front-end bulk-micromachining of the fabricated CMOS dies using electrochemical etch-stop technique in TMAH. Since this approach does not require any lithography or infrared sensitive material deposition after CMOS fabrication, the detector cost is almost equal to the CMOS chip co...
A 2D Slotted Rod Type PhC Cavity Inertial Sensor Design for Impact Sensing
Orsel, Ogulcan Emre; ERDİL, MERTCAN; Kocaman, Serdar (Institute of Electrical and Electronics Engineers (IEEE), 2020-02-01)
A tunable 2D rod type Si Photonic Crystal cavity based impact sensing configuration is proposed and numerically analyzed. The cavity is sandwiched by perfect electric conductor (PEC) boundaries in order to provide out-of-plane light confinement. An on-purpose air slot is introduced between the Si rods and top PEC plate moving the light confinement into the slotted region and making the cavity highly responsive to the displacement of top PEC boundary. Optomechanical coupling strength is calculated to be on t...
Study of strain measurement by fiber optic sensors with a sensitive fiber loop ringdown spectrometer
Kaya, M.; Esentürk, Okan (Elsevier BV, 2020-01-01)
A sensitive fiber loop ringdown (FLRD) spectrometer without any additional optical component was utilized to obtain strain measurement on a single mode fiber optic sensor. The strain data were obtained by employing the theory of bending loss in single mode fibers. The best sensitivity of the sensors was obtained as 5.99 με with an 80.0 cm long sensor head when the sensor heads were stretched at the midpoint. The spectrometer system had a baseline-stability of 0.22%. Stretching the sensor head from off-midpo...
A Compact Energy Transducer for Power Generation From Respiration
Beyaz, Mustafa Ilker; Habibiabad, Sahar; Yildiz, Hamza; Goreke, Utku; Azgın, Kıvanç (Institute of Electrical and Electronics Engineers (IEEE), 2019-06-01)
This paper reports a compact magnetic transducer developed for generating electrical power from respiration. The device incorporates a side-drive turbine rotor with embedded permanent magnets and two stators, integrated into a poly(methyl methacrylate) (PMMA) package for actuation. The novelty and advantage of the design lies in almost full use of the available turbine volume together with two stators for both mechanical and electrical transduction, which leads to high rotational speeds and high voltage gen...
An Adaptable Interface Circuit With Multistage Energy Extraction for Low-Power Piezoelectric Energy Harvesting MEMS
Chamanian, Salar; Ulusan, Hasan; Koyuncuoglu, Aziz; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-03-01)
This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The circuit interfaces a piezoelectric energy harvesting micro electro-mechanical systems (MEMS) device to scavenge acoustic energy. Synchronous electric charge extraction (SECE) technique is deployed through the implementation of a novel multistage energy extraction (MSEE) circuit in 180 nm HV CMOS technology to harvest and store energy. The circuit is optimized to operate...
