1. Introduction The key part of the optical network module that we are proposingg1],2] is a two dimensional optical element consisted of the vertical cavity surface-emitting laser (VCSEL) arrays and the switching devices with optical lter. In this paper, we report on a study of the fabrication technologies of a distributed Bragg reeector (DBR) for VCSEL and optical lter for the switching device...

Abstract This paper reports on design, measurement and optimisation of a Tamm plasmon metal-distributed Bragg reflector (DBR) cavity for use in the green part visible spectrum. It uses an optimised silver layer thickness porous DBR created using novel electro-chemical etching technique. device has applications low-cost lasers, photodetectors, photoconductive switches wavelength range.

In this paper, we optimize the structure of multi-paired SiO2/TiO2 Bragg reflector to obtain broad-band and broad-angled high solar reflectivity in visible near-infrared frequencies. To control refractive index contrast BR pairs, porosity SiO2 (same across all layers) is also allowed change. We study trade-off between number pairs overall performance structure. As a result optimization, demonst...

We report on a channel drop filter with a mode gap in the propagating mode of a photonic crystal slab that was fabricated on silicon on an insulator wafer. The results, simulated with the 3-dimensional finite-difference time-domain and plane-wave methods, demonstrated that an index-guiding mode for the line defect waveguide of a photonic crystal slab has a band gap at wave vector k = 0.5 for a ...

Ten Gb/s low power penalty ( 0 5 dB)error-freetransmission was achieved through 75 km using a high-perfor-mance sampled-grating (SG) distributed Bragg reflector (DBR)laser/EAM transmitter. Large signal chirp measurements shownegative chirp operation across the entire tuning range of the de-vices. An integration-oriented quantum-well-intermixing (QWI)process was emplo...

A polarimetric Distributed Bragg Reflector (DBR) laser sensor in a low birefringent Er-doped fiber has been proposed. The spectral overlap of two uniform fiber Bragg gratings (FBG) has been employed as filtering technique to achieve a Single Longitudinal Mode (SLM) regime. By measuring the RF beat frequency between the two orthogonal polarized lasing modes and the absolute wavelength of one mod...

The molecular beam epitaxy growth of AlAsSb/Al 0.04 Ga 0.96 AsSb distributed Bragg reflectors lattice-matched to InP is studied. The fabrication and characterization of two such reflectors are reported. Fine structural and optical properties of these samples are investigated using double crystal X-ray diffraction, scanning electron microscopy and reflectivity measurements. Main device performan...
