Photonic scanning receiver using an electrically tuned fiber Bragg grating.

Patrik Rugeland, Z. Yu, Christina W Sterner, Oleksandr Tarasenko, Goran Tengstrand, Walter Margulis
Optics letters
2009

A 5-cm-long electrically tuned fiber Bragg grating is used to filter a microwave signal on an optical carrier at 1.55 mum. A chirped distributed-feedback structure is employed, with a transmission… (More)

Study of thermally poled fibers with a two-dimensional model.

Alexandre Sandri Câmara, Oleksandr Tarasenko, Walter Margulis
Optics express
2014

A two-dimensional (2D) numerical model is implemented to describe the movement of ions under thermal poling for the specific case of optical fibers. Three types of cations are considered… (More)

Scanning Electron and Atomic Force Microscopy to Study Plasma Torch Effects on B. cereus Spores

Oleksandr Tarasenko, Seyed Mohammad Kazem Nourbakhsh, +5 authors Kalle Levón
IEEE Transactions on Plasma Science
2006

The occurrence of scanning electron microscopy (SEM) and atomic force microscopy (AFM) side-by-side is becoming increasingly common in analytical research. This article shows microscopy techniques to… (More)

Killing of Bacterial Spores Contained in a Paper Envelope by a Microwave Plasma Torch

S. P. Kuo, Oleksandr Tarasenko, Suzana Popovic, Kalle Levón
IEEE Transactions on Plasma Science
2006

The air plasma effluent of an arc-seed microwave torch is used to kill bacterial spores contained inside an envelope. The torch is operated at a 60-Hz periodic mode (with about 40% duty cycle) and… (More)

Tunable Photonic Microwave Generation Based on a Novel Dual-Polarization Fiber Laser Cavity

Patrik Rugeland, Zhangwei Yu, Oleksandr Tarasenko, Goran Tengstrand, Walter Margulis
IEEE Photonics Technology Letters
2011

A novel dual-polarization fiber laser is proposed by incorporating a distributed feedback grating inscribed in a twin-hole fiber with internal electrodes. Dual-polarization lasing is achieved with a… (More)

Who needs a cathode? Creating a second-order nonlinearity by charging glass fiber with two anodes.

Walter Margulis, Oleksandr Tarasenko, Niklas Myrén
Optics express
2009

We report that it is possible to create a fiber electret by having both internal electrodes of a twin-hole fiber at the same anodic potential, i.e., without the use of a contacted cathode electrode.… (More)

Contribution of a Portable Air Plasma Torch to Rapid Blood Coagulation as a Method of Preventing Bleeding

S. P. Kuo, Oleksandr Tarasenko, +9 authors Hua Fan
2017

The effectiveness and mechanism of a low temperature air plasma torch in clotting blood are explored. Both blood droplets and smeared blood samples were used in the tests. The treated droplet samples… (More)

Electro-optical fiber modulation in a Sagnac interferometer.

The linear electro-optical effect was induced in optical fibers by thermal poling. A Sagnac all-spliced fiber loop was constructed incorporating an electro-optical fiber used as a phase modulator at… (More)

Pulse selection at 1 MHz with electrooptic fiber switch.

Mikael Malmström, Oleksandr Tarasenko, Walter Margulis
Optics express
2012

Two 78-cm long electrooptic fibers with nonlinear coefficient χ((2)) ~0.26 pm/V are used in a Sagnac loop for pulse selection at up to 1 MHz repetition rate. Laser pulses of 1.5 µm wavelength… (More)

Actively Q-switched all-fiber laser with an electrically controlled microstructured fiber.

Zhangwei Yu, Marlene Malmström, Oleksandr Tarasenko, Walter Margulis, Fredrik Laurell
Optics express
2010

Actively Q-switching of an all-fiber laser system is demonstrated. The active element is a polarization switch with nanosecond risetime based on a microstructured fiber with electrically driven… (More)
