A laser model is formulated in terms of quantum harmonic oscillators. Emitters the low lasing states are usual oscillators, and emitters upper inverted Diffusion coefficients, consistent with necessary for solving nonlinear equations analytically, found. Photon number fluctuations mode population calculated. Collective Rabi splitting peaks predicted intensity fluctuation spectra superradiant la...

We have designed and developed a grating based thulium (Tm) doped fiber laser with ~150 nm tuning range which is used as the master oscillator in a master oscillator power amplifier (MOPA) thulium fiber laser system. Due to thermal instability in the grating used for tuning, the MO could produce a power up to 4.5 W, beyond which the oscillator became unstable. Injecting the seed laser into a bi...

Oscillators are an artefact of Electrical Technology. By and large oscillator designing can be viewed as a ‘Scientific Art’. Furthermore, the use of computer in the designing process of oscillator added the wings to it. FuzzyLogic-Computer-Aided-Design (FLCAD) using MATLAB FUZZY TOOLBOX amalgamates the ability of Fuzzy Logic to model colloquial propositions involved in the oscillator design. De...

This paper represents a novel second harmonic power combining oscillator using mutually synchronized Gunn diodes embedded on slot line resonators. A both-sided MIC technology is adopted in the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. By embedding Gunn diodes on slot line resonators, desired harmonic RF signal can be generated very easily. Th...

We study qubit decoherence under generalized dispersive readout, i.e., we investigate a qubit coupled to a resonantly driven dissipative harmonic oscillator. We provide a complete picture by allowing for arbitrarily large qubit-oscillator detuning and by considering also a coupling to the square of the oscillator coordinate, which is relevant for flux qubits. Analytical results for the decohere...

Due to their low cost, design simplicity and ease in practical implementation, for example, MOSFET-based oscillators are widely used in modern wireless handset applications. This three-part tutorial highlights the basics of the oscillator circuit design, setting the relationships between the start-up and steadystate operating modes and the device equivalen...

A completely monolithic high-Q oscillator, fabricated via a combined CMOS plus surface micromachining technology, is described, for which the oscillation frequency is controlled by a polysilicon micromechanical resonator with the intent of achieving high stability. The operation and performance of micromechanical resonators are modeled, with emphasis on circuit and noise modeling of multiport r...
