Phase dependent of DBR gratings

2013 International Symposium on Next-Generation Electronics, 2013
A novel double input DBR grating is presented in this paper. The length of the grating region and the phase difference of the inputs can determine the direction and the efficiency of the output power.th of the grating region and the phase difference of the inputs can determine the direction and the efficiency of the output power.

On the photoelectron spectra of HBr and DBr

Journal of Electron Spectroscopy and Related Phenomena, 1972
Abstract The photoelectron spectra of HBr and DBr with He I (58.4 nm) are discussed. The photoelectron spectrum of DBr confirms the predissociation of the A 2Σ+ electronic state. A rough estimate of the predissociation rate is calculated.

OFDR with an SSG-DBR laser

SPIE Proceedings, 2004
Recently, frequency-domain (FD) -optical-coherence-tomography (OCT) methods have been investigated extensively as more efficient and sensitive system compared with conventional time-domain (TD) -OCT. Superstructure-grating-distributed-Bragg-reflector (SSG-DBR) lasers are particularly suited for optical-frequency-domain-reflectometry (OFDR ...

Numerical design of novel DBR

SPIE Proceedings, 2005
A numerical design of a kind of novel distributed Bragg reflectors (DBRs) which is used in VCSEL with 808nm wavelength is reported. In this DBR, the short period superlattice (SPS) is used for the layers with high refractive index. First, the principle of the DBR with SPS is described, and the special features of the novel DBR are given.
