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.

Tapered, resonant DBR transmission filters

IEEE Photonics Technology Letters, 1993
Wavelength-tunable optical filters, in the form of resonant distributed Bragg reflector laser filters, have been fabricated and evaluated. The devices are specially designed as transmission filters and have a novel structure, using low coupling strength in the grating and an up-tapered active section, in order to improve the crosstalk performance and ...

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.

Microstrip DBR diplexer with DBS

2012 4th International High Speed Intelligent Communication Forum, 2012
A microstrip diplexer with low insertion losses and high isolation is proposed. The transmit — receive (Tx — Rx) filters based on the dual-behaviour resonator (DBR) are designed at the required frequency for the realization of a diplexer. The dual-band stub (DBS) is introduced to improve rejection in the upper stopband of the Rx filter.
