Introduction: Cardiac Magnetic Resonance Imaging (MRI) is an excellent tool in analysis of left ventricular (LV) functioning[3]. Short axis cardiac MR images are most suitable to study the LV function [4], but preparation for generating these images is time consuming and requires sound understanding of the cardiac anatomy. Accurate and reproducible(More)
PURPOSE Augmentation of the alveolar ridge before implant placement is frequently performed. The purpose of this study was to compare the amount and quality of bone formation under Micro Titanium Augmentation Mesh (M-TAM) when used alone for guided tissue regeneration or in combination with a porous hydroxyapatite (HA) bone graft substitute. MATERIALS AND(More)
We construct a high gain high output power 1310 nm hybrid fiber amplifier, which can be use in telecommunication. It is a compact design combining a semiconductor optical amplifier (SOA) and a discrete Raman amplifier. It is hard to construct such amplifier by either using a SOA or a discrete Raman fiber amplifier with compact design. The amplifier is(More)
We demonstrate a 2 µm passive mode-locked fiber laser. A single-wall carbon nanotube (SWCNT) is used as saturable absorber. Thulium-doped fiber (TDF) is used as the gain medium. The output wavelength is grating stabilized to 1998.85 nm by a high reflective (HR) fiber Bragg grating (FBG) together with a two by two coupler. A 8.22 MHz fundamental(More)
A complete 40 Gb/s front-end chip set for optical transmission systems will be presented The analog chip set includes modulator drivers on the transmitter site, and transimpedance amplifier, limiting amplifier and automatic-gain-controlled (AGQ amplifier) on the receiver site. All circuits were designed, fabricated in SHBT technologies and successfully(More)
Generation of super-continuum by using 5 m ultra-high NA silica optical fiber (UHNA3) with core diameter 1.8 µm and mode-field diameter (MFD) ∼2.6µm is compared with Photonic Crystal Fiber (PCF). A 1064 nm gained switched pico-second semiconductor pulsed laser source is used to study the performance of supercontinuum generation and the(More)
