TL;DR: In this article, an efficient methodology for detecting magnetic field and thereby magnetic patterns using an injection-locked spin-torque nano-oscillator (STNO) array is proposed.
Abstract: In this paper, we propose an efficient methodology for detecting magnetic field and thereby magnetic patterns using an injection-locked spin-torque nano-oscillator (STNO) array. We demonstrate the methodology with the implementation of a physical STNO model based on the Landau–Lifshitz–Gilbert–Slonczewski equation, which is benchmarked with experimental data. Based on our simulations, we provide an analysis of how the STNO, as a field-controlled oscillator, together with injection locking, can be used to sense magnetic fields and thereby magnetic patterns. The output can be sensed using simple CMOS peripheral circuitry.

TL;DR: In this paper, a multiwavelength injection-locking in a single Fabry-Perot laser diode was used for simultaneous all-optical header processing and packet switching.
Abstract: Simultaneous all-optical header processing and control- packet switching are demonstrated by using multiwavelength injection- locking in a single Fabry-Perot laser diode. A special two-level control packet is used to process the header of the data packet at 5 Gb/s. The entire control packet is all optically switched ON or OFF. © 2005 Wiley Periodicals, Inc.

TL;DR: In this paper, an injection-locked oscillator in combination with a phase detector is shown to make a very effective FM demodulator, which allows automatic tuning from outside the locking range.
Abstract: An injection-locked oscillator in combination with a phase detector is shown to make a very effective FM demodulator. The dynamic behavior is similar to a PLL but with several advantages, one of which allows automatic tuning from outside the locking range.

TL;DR: Theoretical results indicate that by using hybrid integration to shorten the cavity length, nanosecond-order locking time can be achieved, which is critical for a variety of applications such as protection switching, optical burst and optical packet switching.
Abstract: We describe an optical clock recovery circuit that employs a traveling-wave electroabsorption modulator-based ring oscillator. This approach provides synchronized optical clock and the original optical data signal from the same output at separate wavelengths, eliminating additional timing adjustments for the subsequent nonlinear decision gate for reamplifying, reshaping, and retiming (3R) regeneration. Furthermore, additional retiming and lateral reshaping of the original data signal can be realized along with optical clock recovery by synchronized modulation. We present a general model of jitter transfer and locking dynamics for the clock recovery circuit and compare with experimental results. Theoretical results indicate that by using hybrid integration to shorten the cavity length, nanosecond-order locking time can be achieved, which is critical for a variety of applications such as protection switching, optical burst and optical packet switching. Experimental demonstrations of 40-Gb/s optical clock recovery and its application for optical 3R regeneration are presented. The recovered 40-GHz optical clock has 500-fs timing jitter and 8-ps pulsewidth, and within 0.3 /spl mu/s locking time. 3R experiment is implemented by using the OCR combined with a subsequent regenerative wavelength converter, which provides vertical reshaping function. 3R regeneration is demonstrated with a reduced timing jitter.
