Below-band-gap waveguiding behaviors of a weakly index-guided GaAs/AlGaAs quantum well laser
We report the reduced waveguiding efficiency for the signals around 1560 nm as the injection current of an GaAs/ AlGaAs multiple quantum well laser diode (lasing wavelength at 840 nm) with a ridge-loading waveguide configuration increased. This reduction trend stopped when the injection current reached the threshold condition of the laser diode. The decreased waveguide transmission and the more...
متن کاملThe Effect of Structural Parameters on the Electronic States and Oscillator Strength of a Resonant Tunneling Quantum Well Infrared Photodetector
In this paper a resonant tunnelling quantum well infrared photodetector (RT-QWIP) is discussed. Each period of this photodetector structure comprises of a resonant tunnelling structure (AlAs/AlGaAs/AlAs) nearby a quantum well (AlGaAs/GaAs). In this photodetector, photocurrent is produced when an electron makes a transition from the ground state of the well to an excited state which is coupled t...
متن کاملGain optimization of the optical waveguide based on the quantum box core/shell structure
In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...
متن کاملOptical Loss and Lasing Characteristics of AlGaAs Microdisk Cavities with Embedded Quantum Dots
For future experiments in cavity QED with self-assembled quantum dots, the GaAs/AlGaAs system is the most appropriate choice of material, due to the relative maturity of the growth of InAs/InGaAs quantum dots [138, 139, 140] within this system. As the refractive index of GaAs and its alloys is relatively close to that of Si (n GaAs ∼ 3.5 and n AlAs ∼ 2.9 at λ ∼ 1.25 µm), the PC cavity design of...
