Interaction between surface plasmon polaritons and molecules in strong coupling limit
2016
Miniaturization of optical elements and their integration to electronic circuits is limited by diffraction limit. It was realized that light being coupled to surface plasmons (SP) can overcome this limit. Employing also optically active molecules in combination with SPs can drive optical circuits to nm-scale and add functionalities. For efficient performance of plasmonic elements involving fluorescent dye molecules investigation of physics behind their interaction is of high priority. In this thesis interaction between surface plasmon polaritons (SPPs) and different dye molecules has been studied, especially within strong coupling limit, which brings in totally new physical properties in th…
Theory of phase-mixing amplification in an optomechanical system
2017
The investigation of the ultimate limits imposed by quantum mechanics on amplification represents an important topic both on a fundamental level and from the perspective of potential applications. We discuss here a novel regime for bosonic linear amplifiers—beside phase-insensitive and phase-sensitive amplification—which we term here phase-mixing amplification. Furthermore, we show that phase-mixing amplification can be realised in a cavity optomechanical setup, constituted by a mechanical resonator which is dispersively coupled to an optomechanical cavity asymmetrically driven around both mechanical sidebands. While, in general, this amplifier is phase-mixing, for a suitable choice of para…
Pyhäpäivien vietto varhaismodernin ajan Savossa (vuoteen 1710)
2016
In this dissertation, I study the observance of holy days among the peasantry in the early modern province of Savo, located on the eastern periphery of the Swedish kingdom (today Eastern Finland). I examine the practices, norms and meanings related to the observance of holy days both within and outside the Church, and analyse the changes and continuities in the post-reformation period. As the main sources of the study, I use district court records and visitation records mainly from the period 1639–1712. I analyse the cases with a micro-historical perspective and an anthropological approach. The lived religion of the peasantry was constituted especially through practices that were connected …
