GaAs-GaAlAs Double-Heterostructure Injection Lasers with Distributed Feedback
GaAs-GaAlAs double-heterostructure distributed-feedback injection lasers are investigated a t temperatures between 80 and 150 K under pulsed operation. The optical feedback for laser oscillation is provided by a corrugated interface between the p-GaAs active layer and the pGaA1As layer. The corrugation is made by two methods, ion milling and chemical etching, and the latter method is found to g...
متن کاملGaAs/GaAIAs Injection Laser
Absrmct-The temporal coherence of a stripe-geometry doubleheterojunction GaAs/GaAlAs laser operating CW at room temperature was determined. A heterodyne detection scheme was used involving the mixing of the laser field with a frequency-shifted and time-delayed image of itself in an interferometer. Because the laser device oscillated in several longitudinal modes, the autocorrelation functio...

متن کاملPiezoresistive InGaAs/GaAs nanosprings with metal connectors.
This paper presents the fabrication, assembly, and characterization of piezoresistive nanosprings for creating nanoelectromechanical systems. The fabrication process is based on conventional microfabrication techniques to create a planar pattern in a 27nm thick, n-type InGaAs/GaAs bilayer that self-forms into three-dimensional structures during a wet etch release. As the nanosprings have lower ...
متن کاملInverted Solution Processable OLEDs Using a Metal Oxide as an Electron Injection Contact
A new type of bottom-emission electroluminescent device is described in which a metal oxide is used as the electron-injecting contact. The preparation of such a device is simple. It consists of the deposition of a thin layer of a metal oxide on top of an indium tin oxide covered glass substrate, followed by the solution processing of the light-emitting layer and subsequently the deposition of a...
