Characterization of Distributed Bragg Reflectors
IEEE Journal of Quantum Electronics, 2014We propose and demonstrate a novel method to characterize the coupling coefficient and loss coefficient of a distributed Bragg reflector (DBR). The method is based on a coupled-mode analysis of periodic structures, and involves the linewidth comparison of a pair of DBR Fabry-Perot resonators. The method is shown to be independent of coupling efficiency

AlP/GaP distributed Bragg reflectors
Applied Physics Letters, 2013Distributed Bragg reflectors with high reflectivity bands centered at wavelengths from 530 to 690 nm (green to red) based on AlP/GaP quarter-wave stacks are prepared on (001)GaP using gas-source molecular-beam epitaxy. Additionally, the complex refractive index of AlP is measured using spectroscopic ellipsometry within the range of 330–850 nm in order ...

Hybrid Distributed Bragg Reflector Laser
CLEO/Europe Conference on Lasers and Electro-Optics, 1998Current and future WDM (Wavelength Division Multiplexing) optical systems for access and transport networks require stable, low-chirp and potentially low cost lasers emitting at predetermined (ITU-T grid) wavelengths. In addition advanced OTDM (Optical Time Division Multiplexing) systems require sources for high quality picosecond pulses on the ...

Waveguide Resonators with Distributed Bragg Reflectors
Optica Acta: International Journal of Optics, 1982The transmission and reflection properties of a waveguide resonator with DBRs are described near and at the Bragg condition using the method of coupled waves. Different grating configurations characterized by their coupling coefficients, attentuation parameters, and geometric dimensions are included to investigate symmetrical and asymmetrical resonator

GaAs distributed Bragg reflector lasers
Optics Communications, 1976Abstract An equivalent cavity approach is used to derive the oscillation condition of a distributed Bragg reflector laser. The oscillation frequencies and thresholds are determined graphically. The effect of lossy reflectors is discussed. Several advantages and potential applications of distributed Bragg reflector structures are pointed out ...

High q-factor distributed bragg reflector resonators with reflectors of arbitrary thickness
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007The Bragg reflection technique improves the Q-factor of a resonator by reducing conductor and dielectric losses. This is achieved by designing a low-loss inner resonant region (usually free space) surrounded by an outer anti-resonant region made of distributed Bragg reflector layers.

High performance distributed Bragg reflector microwave resonator
Proceedings of 1996 IEEE International Frequency Control Symposium, 1997A new resonator device structure is described that achieves Q-factors well above those currently realizable for conventional room temperature microwave structures. The new structure consists of a microwave cavity, for which the enclosure walls consist of distributed Bragg reflectors (DBR) made of low-loss sapphire.

High-power GaInAs lasers with distributed bragg reflectors
Digest of Conference on Optical Fiber Communication, 1992Single-mode strained-layer lasers have been fabricated which use buried second-order gratings for distributed Bragg reflectors. The lasers contain a strained GaInAs quantum well in the active region and operate in an edge emitting fashion with CW powers in excess of 110 mW.
