Integrated external cavity distributed Bragg reflector laser

Applied Physics Letters, 1987
The fabrication and performance characteristics of single frequency integrated external cavity distributed Bragg reflector lasers are described. The current is confined to the active region of these lasers using semi-insulating Fe-doped InP layers. The semi-insulating layer also provides lateral index guiding to the lasing optical mode both in the ...

Self-focused distributed Bragg reflector laser diodes

Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003
Summary from only given. We have reported the successful realisation of the type of a curved-grating DBR semiconductor laser that was previously proposed theoretically. Single-frequency generation was observed and far-field measurements showed good agreement with our prediction for lateral beam behaviour.

Structural analysis of distributed Bragg reflector mirrors

Vacuum, 2009
Abstract Quantum cascade (QC) lasers and vertical-cavity surface-emitting lasers (VCSELs) are of great interest due to their potential importance for a variety of device applications. Both kinds of lasers call for very highly reflective mirrors. Usually distributed Bragg reflector (DBR) mirrors, which consist of periodic quarter wavelength stacks of ...

Organic optical microgravity with distributed Bragg reflectors

SPIE Proceedings, 2001
The single layer of organic optical microcavity with 1D distributed Bragg reflectors (DBRs) was fabricated. The PL emission properties of the microcavity were explored at the two sides, which show different characteristics due to the asymmetric structure. The PL emission peak of Alq film is at 5113 nm with a half width of 78nm.

Improved simulation of VCSEL distributed Bragg reflectors

Journal of Computational Electronics, 2007
In this paper, the Floquet-Bloch theory (FBT) has been applied to the accurate simulation of distributed Bragg reflectors in vertical cavity surface emitting lasers (VCSELs). A number of comparisons with other methods largely used in commercial CAD tools is presented. Performance predictions for long-wavelength GaInAsP VCSELs are derived.

Nanowire lasers with distributed-Bragg-reflector mirrors

Applied Physics Letters, 2006
A self-consistent, coupled optoelectronic simulation model is used to study microcavity GaN nanowire lasers. This model is applied to show that it is possible to design a nanowire laser with distributed-Bragg-reflector mirrors. Several advantages are expected to be enjoyed from the use of such mirrors.

Tunable narrow linewidth distributed Bragg reflector lasers

Conference Proceedings. LEOS'98. 11th Annual Meeting. IEEE Lasers and Electro-Optics Society 1998 Annual Meeting (Cat. No.98CH36243), 2002
We present details of the fabrication and characterization of laser structures, including measurements of the laser emission linewidth and DBR tuning range. Similar results on long wavelength InGaAsP-InP DBR lasers with first-order gratings will be described.
