Bistability and optical control of a distributed-Bragg-reflector laser
Optics Letters, 1993We demonstrate bistable operation and optical control of a specially designed distributed-Bragg-reflector laser. Optically controlled turn-on and turn-off with 1-pJ pulses at 1.5 μm and 2-pJ pulses at 1.3 μm, respectively, is demonstrated as well as all-optical flip-flop operation.

Conductive Inorganic–Organic Hybrid Distributed Bragg Reflectors
Advanced Materials, 2015A conductive hybrid distributed Bragg reflector (DBR) is demonstrated, consisting of inorganic and organic semiconductor films and assembled by a thermal deposition technique. A maximum reflectance of 92.2% and a wide spectral width of more than 70 nm are achieved.

Distributed Bragg reflector made of CdSe and ZnTe
Superlattices and Microstructures, 2020Abstract Distributed Bragg reflector (DBR) is a multilayer periodic structure with a high reflectance of the light due to the constructive interferences. Applications of DBRs include lasers, solar cells, photo-detectors, microcavities, and various photonic structures.

Solgel grating waveguides for distributed Bragg reflector lasers
Optics Letters, 1999Solgel grating waveguides and their application to the fabrication of external-cavity distributed Bragg reflector (DBR) lasers are demonstrated. A new composition of aluminosilicate material is developed for the fabrication of single-mode waveguides and Bragg reflectors. An average loss of

Switching characteristics of distributed Bragg reflector lasers
[Proceedings] Singapore ICCS/ISITA `92, 1992This paper presents numerical results concerning wavelength switching of multisection DBR lasers. The static tuning characteristics and the dynamic behavior of the switching between different longitudinal modes is investigated. The influence of hysteresis in the frequency versus grating current characteristics on the forward and backward switching time

Distributed Bragg Reflector Laser
2018A laser consisting of a distributed-Bragg-reflector (DBR) having a strong wavelength selection mechanism in its reflectivity due to periodicity in the refractive index of the waveguide or the resonator, is called as a DBR laser. A laser consisting of a periodic structure on an active region is called a distributed feedback (DFB) laser, in which ...

Distributed Bragg reflectors: Morphology of cellulose acetate and polystyrene multilayers
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014The optical quality and photonic properties of all-polymer distributed Bragg reflectors are related to the morphology of the layers and the optical responses of the materials. We introduce the X-ray reflectivity method to determine the thickness, the interface- and surface-roughness of cellulose acetate and polystyrene layers which are two polymers ...

Analysis of Distributed Bragg-Reflector Laser Amplifiers
Japanese Journal of Applied Physics, 1977Laser amplifiers with distributed Bragg-reflectors are analyzed to obtain the transmission gain and the linewidth by using the coupled-mode equation. Compared with the distributed feedback (DFB) laser amplifiers, the distributed Bragg-reflector (DBR) laser amplifiers have an advantage that the transmission gain and the linewidth are controlled by the ...

Organic optical microgravity with distributed Bragg reflectors
SPIE Proceedings, 2001The 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.

Structural analysis of distributed Bragg reflector mirrors
Vacuum, 2009Abstract 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 ...
