Injection Locking of VCSELs
Injection locking has been actively researched for its possibility to improve laser performance for both digital and analog applications. When a modulated follower laser (also termed “slave” laser) is locked to the master laser, its nonlinear distortion and frequency chirp may be reduced. As well, the resonance frequency can increase to several times higher than its free running case. In this p...
متن کاملdesigning a fast locking pll
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Reflection-mode optical injection locking.
A novel model including the interference effect of master laser reflection is established for reflection-mode optical injection locking. This model sheds insight on the physical origin of some rather distinct but unexplained modulation characteristics of optical injection-locked vertical-cavity surface-emitting lasers (VCSELs), including data pattern inversion in on-off keying modulation, a lar...
متن کاملPound-locking for characterization of superconducting microresonators.
We present a new application and implementation of the Pound-locking technique for the interrogation of superconducting microresonators. We discuss how by comparing against stable frequency sources this technique can be used to characterize properties of resonators that cannot be accessed using traditional methods. Specifically, by analyzing the noise spectra and the Allan deviation, we obtain ...
متن کاملPhase-locking transition in a chirped superconducting Josephson resonator.
We observe a sharp threshold for dynamic phase locking in a high-Q transmission line resonator embedded with a Josephson tunnel junction, and driven with a purely ac, chirped microwave signal. When the drive amplitude is below a critical value, which depends on the chirp rate and is sensitive to the junction critical current I0, the resonator is only excited near its linear resonance frequency....
