Compact and Efficient Femtosecond Supercontinuum Sources
ISBN: 9783838110738 / Angielski / Miękka / 148 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work deals with the realization of compact and multi-Watt femtosecond supercontinuum sources based on diode-pumped laser oscillators and highly nonlinear glass fibers. Micro-structured fibers, either tapered fibers or photonic crystal fibers (PCF), can convert narrow band laser light into multiple octave broad spectra. Average powers of several Watts and conversion efficiencies of more than 50 % can be achieved. In the femtosecond regime, a unique property of those spectra is a high spectral phase coherence. The main part of this thesis describes the development of two diode-pumped...

Coupling of Quantum Dots to Photonic Crystal Nanocavities
ISBN: 9783838109602 / Angielski / Miękka / 160 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Recently, the emission of single photons with wavelength in the 1.3um telecommunication window was demonstrated for InAs quantum dots. This makes them strong candidates for applications such as quantum cryptography, and in a longer term, quantum computing. However, efficient extraction of the spontaneous emission from semiconductors still represents a major challenge due to total internal reflection at the semiconductor/air interface. This thesis work explores the integration of quantum dots, with emission at 1.3um, in photonic crystal microcavities. Photons emitted in a mode of the cavity...

In the Indian scenario it was around the late 1980s early 1990s that TV and Cable TV as well as the internet has suddenly acquired a major growth leading to widespread belief that Radios days were numbered and this convenient and effective mass medium was pushed to corner. The researcher intended to study in-depth whether this belief was true or not and has completed the study to finally conclude that Radio has managed to survive this onslaught and survive in a healthy manner. It was be found that Radio has accepted the challenge of the audio-visual medium in its stride and has...

Fricative Analyses using Two Area Derivation Techniques
ISBN: 9783639279320 / Angielski / Miękka / 304 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. It is still unclear to speech scientists how the brain is able to distinguish fricative sounds from the many cues within the speech signal. The work here makes an acoustic and aticulatory investigation into the problem, using fricative utterances and magnetic resonance (MR) images. The objective is to determine the perceptually important features of the fricative sound, by comparing the acoustic spectra and synthetic sounds derived from two area-derivation methods known as the Mermelstein technique and the Blum transform which are distinct from one other in terms of the treatment of...

Real-time Protection of Scalable Video Content
ISBN: 9783639299540 / Angielski / Miękka / 224 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work is focused on protection of state of the art video bitstreams and their scalable extensions. For copyright protection and meta-data embedding, we opt for watermark embedding with very controlled compromise on PSNR and bitrate. The secret lies in the fact that the reconstruction loop has taken into account to avoid the mismatch on the encoder and decoder. Spread spectrum watermarking was then implemented on QTCs inside the reconstruction loop. It is, later on, used to embed Tardos fingerprinting code to avoid traitor tracing. For restriction of access only to authorized users,...

Cryogenic Bulk Acoustic Wave Resonators and Oscillators
ISBN: 9783846588420 / Angielski / Miękka / 212 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Nowadays, the best short-term frequency stability performance is achieved with quartz crystal oscillators. But now it is generally believed that this family of frequency sources is almost in saturation and could not lead to considerable stability improvement with reasonable efforts in the future. So, a jump of technology is necessary. The possibility of replacement of quartz oscillators with MEMS and chip-scale atomic clocks is under discussion. As for the long term stability performance, many different types of frequency sources compete. Here, atomic clocks, hydrogen masers, cryogenic...
