Phase-Controlled Apertures Using Heterodyne Optical Phase-Locked Loops [PDF]
, 2008 In this letter, we demonstrate the use of an electronic feedback scheme using a voltage controlled oscillator (VCO) to control the optical phase of individual semiconductor lasers (SCLs) phase locked to a common reference laser using heterodyne optical ...

The Phase-Locked Loop and Costas Loop
International Journal of Contemporary Research and Review, 2017 In this study, the classical phase-locked loop (PLL) and Costas loop are investigated together. How the synchronization is obtained by the carrier recovery from the sinusoidal reference signal is mathematically shown with some assumptions and presented. It is concluded from this paper that Costas loop produces about half of the error signal produced by

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine
Advanced Robotics Research, EarlyView.This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Noise in Phase-Locked Loops [Invited]
, 2001 Jitter and phase noise properties of phase-locked loops (PLL) are analyzed, identifying various forms of jitter and phase noise in PLLs. The effects of different building blocks on the jitter and phase noise performance of PLLs are demonstrated through a
