Linear and nonlinear optical properties of a modified Gaussian quantum dot: pressure, temperature and impurity effect

In this paper, the effect of pressure, temperature and impurity on the energylevels, binding energy, linear and nonlinear optical properties of a modified Gaussianquantum dot are studied. In this regard, the finite element method is employed to solvethe single electron Schrodinger equation in the effective mass approximation with andwithout impurity at the center of the dot. In addition, the en...

A novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler

In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...

Optical ASK and FSK Modulation By Using Quantum Well Transistor Lasers

In this paper, transistor lasers (TLs) are used as an optical modulator for generation of ASK(Amplitude Shift Keying) and FSK (Frequency Shift Keying) optical signals. Our analysis is based on continuity equation, rate equations, and the theory of discontinuity of quasi-fermi level at the abrupt junction. Our simulation results indicate that, the specification of ASK and FSK optical signals, ar...

Quantum phase gate for photonic qubits using only beam splitters and postselection

The main difficulty in realizing quantum computation and quantum-information processing for single photon qubits is the optical implementation of controlled interactions between individual qubits. A deterministic interaction between separate photons would require the ability to apply strong nonlinearities during well-defined time intervals @1#. At present, there are still many technological dif...
