A distributed feedback silicon evanescent laser
Optics Express, 2008 We report an electrically pumped distributed feedback silicon evanescent laser. The laser operates continuous wave with a single mode output at 1600 nm. The laser threshold is 25 mA with a maximum output power of 5.4 mW at 10 degrees C. The maximum operating temperature and minimum line width of the laser are 50 degrees C, and 3.6 MHz, respectively.

Helical distributed feedback Gaslaser
1983 Eighth International Conference on Infrared and Millimeter Waves, 1982Theory, realization and mode characteristics of a helical distributed feedback far-ir gas laser are presented. In this laser DFB is provided by a structure of helical symmetry contrary to standard DFB lasers which are based on linear periodic modulations.

Feedback Control for Distributed Manipulation
2004We consider the feedback stabilization of a part being manipulated by a distributed array of actuators. Previously, the authors showed that open loop methods based on programmable vector fields can lead to unstable dynamics, particularly when the effects of rolling and sliding against actuators play a significant role in the dynamics.

Matching of distributed-feedback structures
Optics Letters, 1992Distributed-feedback structures may provide the increased dispersion required for soliton switching when materials with increased nonlinearity become available. Over the bandwidth of the pulses used, the structure will have to appear matched to the input and output.

Feedback in distributed amplifiers
IEEE Transactions on Microwave Theory and Techniques, 1990A model is presented for parallel and series feedback effects in distributed amplifiers, and their frequency-dependence characteristics are discussed. A six-element distributed amplifier utilizing series feedback is described. The results show a 2-dB improvement in small-signal gain over the 2-18-GHz frequency range compared to a conventional ...

All of the lasers that have been described so far depend on optical feedback from a pair of reflecting surfaces, which form a Fabry-Perot etalon. In an optical integrated circuit, in which the laser diodes are monolithically integrated within the semiconductor wafer, it is usually very difficult to form such reflecting surfaces.

Multicore fiber distributed feedback lasers
Optics Letters, 2012We demonstrate parallel fabrication of seven fiber distributed feedback (DFB) lasers in a hexagonally arrayed multicore core Er doped fiber with 40 μm core spacing. DFB grating cavities 8 cm long and operating near 1545 nm were fabricated with a single UV inscription exposure.

2013 IEEE XXXIII International Scientific Conference Electronics and Nanotechnology (ELNANO), 2013
A new technique for circuit feedback analysis is presented. A formula for the return ratio is derived using a strict definition of feedback. The technique may be applied in both laboratory-based and computer-aided analysis of feedback in electronic circuits and other dynamic systems.

Cross-distribution Feedback in Software Ecosystems
Proceedings of the IEEE/ACM 42nd International Conference on Software Engineering Workshops, 2020Despite the proliferation of software ecosystems (SECOs), growing a sustainable and healthy SECO remains a significant challenge. One approach to mitigate this challenge is the utilization of a mechanism that collects feedback from distributors (distros) and end-users of the SECO releases.
