Stability Analysis of Quantum-Dot Spin-VCSELs
Spin-polarized vertical-cavity surface-emitting lasers (spin-VCSELs) and vertical external-cavity surface-emitting lasers (spin-VECSELs) are of interest since their output polarization can be manipulated by spin-selective pumping, either optical or electrical. These devices, using quantum dot (QD) material for the active region, have shown instability (periodic oscillations) and polarization sw...
متن کاملOptical Modes In VCSELs
Consider the typical VCSEL structure in Figure 1. In this example, the gain region consists of three quantum wells placed in a onewavelength thick spacer region. On either side of the spacer region, there are extremely high reflectivity mirrors made from semiconductors that have total reflectivity greater than 99.5%. The mirrors are fabricated from altering material layers that are λ/4 thick to...

متن کاملModulating VCSELs
One of the foremost applications of VCSELs is to transmit optical signals. These signals require modulation of the VCSEL to vary its emitted power. This note provides information about VCSEL modulation that may assist in the design of optical transmitters. While many of the same principles apply to analog modulation applications, this note is aimed primarily at digital applications where data i...
متن کاملQuantum Error Correction in correlated quantum noise
The superiority of quantum computation over conventional computation relies on the fact that a quantumbit (qubit) register can be in the superposition of a very large number of classical computational states. At the same time, maintaining coherence of this highly superpositional state poses also the main obstacle for the realization of a quantum computer. For a small number of qubits this diffi...
