We study the spontaneous emission spectra of optically pumped vertical-cavity surface-emitting lasers (VCSELs) operating below threshold. By spatial and angular filtering of the spontaneous emission spectra we can relate the observed asymmetrical sha

The polarization anisotropy of ordered GaInP has been studied in electroluminescence and electroabsorption and has been applied to some optoelectronic device structures, operating at . Surface-emitting light emitting diodes (LEDs) have been fabricate

A detailed experimental characterization of the dynamics of Vertical Cavity Surface Emitting Lasers (VCSELs) is presented. Evidence of strong anticorrelations between the different states of linear polarization of the field is given. As a consequence

We report that the polarization of the emission of an optically pumped vertical-cavity surface-emitting laser (VCSEL) is sensitive to the polarization state of the pump light. By measuring this memory effect for circularly polarized pump light, we de

Recently, we have demonstrated that the ambipolar diffusion constant in n-i-p-i strctures exceeds the values of corresponding bulk materials by typically two to three orders of magnitude. After outlining the physical origin of this anomaly we discuss

Birefringence induced by the electro-optic effect is demonstrated in vertical-cavity surface-emitting lasers (VCSEL). This is done by comparing two types of optically pumped VCSELs: VCSELs with standard pin-doping and VCSELs with symmetrical pip-dopi

We have investigated the electroabsorption due to the Franz–Keldysh effect in GaInP/AlGaInP p-i-n double heterostructures grown by metalorganic vapor phase epitaxy. The simultaneous evaluation of transmission and photocurrent measurements allowed a

A cascadable, optical differential amplifier with an active output is realized in AlGaAs-GaAs by the monolithic integration of three devices: A photodiode (PD), a light-emitting diode (LED) and a combination of a photodiode and a junction field-effec

Summary form only given. Top and bottom emitting 1D and 2D VCSEL arrays offer new perspectives in optical and electrical packaging and are therefore of high interest for future short haul parallel optical links, board-to-board and on-board high-speed
