Temperature Dependence of Electrical and Optical Modulation Responses of Quantum-Well Lasers
We present theory and experiment for high-speed optical injection in the absorption region of a quantum-well laser and compare the results with those of the electrical injection in cluding carrier transport effect. We show that the main difference between the two responses is the low-frequency roll-off. By using both injection methods, we obtain more accurate and consistent measurements of man...
متن کاملOptical 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...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Temperature Effect on THz Quantum Cascade Lasers
A simple semi-phenomenological model, which accurately predicts the dependence of thresholdcurrent for temperature of Resonant-phonon three well quantum cascade laser based on verticaltransitions is offered. We found that, the longitude optical phonon scattering of thermally excitedelectrons is the most important limiting factor for thermal performance of high frequency THz QCLs.In low frequenc...
متن کاملTemperature Dependence of Dynamic and DC Characteristics of Quantum-Well and Quantum-Dot Lasers: A Comparative Study
Dynamic and static characteristics of high-speed 1.55and 1m wavelength tunneling injection quantum-well lasers and 1m wavelength self-organized quantum-dot lasers, have been measured as a function of temperature. While differential gain of the quantum-well lasers greatly increased with lowering of temperature (by a factor of 50), gain compression increased along with it, resulting in about the ...
