Synthesis, design and characterization of a distributed feedback grating based non-linear optical chemosensor
… with which we have focused our efforts is the Distributed Feedback (DFB) laser cavity. The waveguide materials synthesized are Si and Ti inorganic matrices that were optimized for optical waveguiding by determining the appropriate film thickness, refractive index and film smoothness. Amplified …

The development of components for ultrafast all-optical communication networks
… Division Multiplexed (WDM) propagation is the distributed feedback (DFB) laser. A periodic index modulation, typically buried within the device structure (hence requiring an overgrowth step), is used to select the specific operating wavelength of the laser. As the WDM wavelength spacing …

Fiber Bragg Gratings Strain Sensors for Railway Applications
… a low cost fiber-optic sensor system with a distributed feedback (DFB) laser as the light source has been implemented. We show that it has superior noise and sensitivity performances compared to strain gauge sensors. The design has been extended to accommodate multiple sensors with negligible …

Label-free biosensor based upon a vertically emitting distributed feedback laser
… for the fabrication of solid state organic distributed feedback laser (DFB) biosensors. The combined techniques enable the organic DFB laser to be uniformly fabricated over large surface areas upon a flexible plastic substrate, with an approach that is compatible with roll-based …

Polarization multiplexed photonic integrated circuits for 100 Gbit/s and beyond
… out in a serial configuration. Furthermore, a laser source is monolithically integrated. All devices are realized in the semiconducting material system of indium phosphide (InP) and its related quaternary alloys (InGaAsP). The technology used for fabrication is referred to as generic, meaning …
