C-band optical filters with micromechanical tuning
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2018)
Tunable optical filters that cover the entire range of the C-band (1530-565 nm) are designed by utilizing the Vernier effect, i.e. series coupling of microring resonators of different sizes, and the micromechanical tuning ...
RF phase noise filtering properties of an actively mode-locked laser
(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA, 2018)
In this article, we are presenting the experimental results and theoretical analysis of radio frequency (RF) phase noise filtering properties of a high Q cavity actively driven mode-locked laser. The experimental results ...
Cascade sliding mode-based robust tracking control of a magnetic levitation system
(SAGE PUBLICATIONS LTD1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND, 2016)
Magnetic levitation systems are able to provide frictionless, reliable, fast and economical operations in wide-range applications. The effectiveness and applicability of these systems require precise feedback control designs ...
Iterative image reconstruction using non-local means with total variation from insufficient projection data
(IOS PRESSNIEUWE HEMWEG 6B, 1013 BG AMSTERDAM, NETHERLANDS, 2016)
In this work, algebraic reconstruction technique (ART) is extended by using non-local means (NLM) and total variation (TV) for reduction of artifacts that are due to insufficient projection data. TV and NLM algorithms use ...
Highly Efficient Cd-Free Alloyed Core/Shell Quantum Dots with Optimized Precursor Concentrations
(AMER CHEMICAL SOC1155 16TH ST, NW, WASHINGTON, DC 20036, 2016)
The chemical composition, the emission spectral bandwidth, and photoluminescence quantum yield of a semiconductor quantum dot (QD) play an important role in the assessment of the performance of the applications related to ...
Performance improvements of photonic lantern based coherent receivers
(IEEE, 2014)
In this work, the signal-to-noise ratio improvement of photonic lantern-based coherent receivers over single-mode coherent receivers is demonstrated. The signal-to-noise ratio is improved by a factor of 2.8 when other ...

(IOP PUBLISHING LTDTEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND, 2016)
Colloidal quantum dots have attracted significant interest in recent years for lighting and display applications and have recently appeared in high-end market products. The integration of quantum dots with light emitting ...
Chaotic Map Construction from Common Nonlinearities and Microcontroller Implementations
(WORLD SCIENTIFIC PUBL CO PTE LTD5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE, 2016)
This work presents novel discrete-time chaotic systems with some known physical system non-linearities. Dynamic behaviors of the models are examined with numerical methods and Arduino microcontroller-based experimental ...
Design of Wide-Band Tunable Optical Filters with Cascaded Microring Resonators and Shaped-Finger Comb-Drive Actuators
(IEEE345 E 47TH ST, NEW YORK, NY 10017 USA, 2016)
Utilizing the Vernier effect, series coupling of multiple microring resonators with different sizes is used to design a wide-band (free spectral range: 36 nm) tunable filter. For index modulators that shift the filter ...
