We study injection locking of two different spin wave (SW) modes (a field-localized linearlike interior mode and a self-localized SW bullet soliton) in single nanoconstriction-based Hall nano-oscillator. Mode selection is achieved by varying the oblique magnetic field angle magnitude. The show dramatically responses to locking, terms bandwidth linewidth output power locked state. Extracting ran...

For fully autonomous implantable or body-worn devices running on harvested energy, the peak and average power dissipation of the radio transmitter must be minimized. We propose a highly integrated 90μW 400MHz MICS band transmitter with an output power of 20μW leading to a 22% global efficiency — the highest reported to date for such systems. We introduce a new transmitter architecture based on ...

This article presents the experimental demonstration of synchronization two integrated semiconductor distributed Bragg reflector lasers, fabricated with a generic multiproject wafer platform, by means injection locking. Substantial linewidth reduction and frequency stabilization lasers were shown during locking to an optical comb. Phase noise was measured for different injected powers laser cav...

There has been considerable interest in exploiting the spin degrees of freedom of electrons for potential information storage and computing technologies. Topological insulators (TIs), a class of quantum materials, have special gapless edge/surface states, where the spin polarization of the Dirac fermions is locked to the momentum direction. This spin-momentum locking property gives rise to very...

We introduce and report recent developments on a novel five port optoelectronic voltage controlled oscillator consisting of a resonant tunneling diode (RTD) optical-waveguide integrated with a laser diode. The RTD-based optoelectronic oscillator (OEO) has both optical and electrical input and output ports, with the fifth port allowing voltage control. The RTD-OEO locks to reference radio-freque...

Previous investigations of noise in mutually synchronized coupled-oscillator systems are extended to include the effects of phase noise introduced by externally injected signals. The analysis is developed for arbitrarily coupled arrays and an arbitrary collection of coherent injected signals, and is illustrated with the specific case of linear chains of nearest neighbor coupled oscillators eith...

This paper discusses the design and implementation of an inductorless differential VCO with a maximum oscillation frequency of 20 GHz, in a 47 GHz SiGe process technology. The VCO is based on a full-wave rectification frequency-doubling technique, applied to a half rate differential single-stage feedback oscillator. It also benefits from a new circuit phenomenon named hereinafter Self Injection...

It has been shown that strong optical injection locking can significantly enhance the resonance frequency of semiconductor lasers. In this Letter, we describe the trade-off between the maximum resonance frequency enhancement and the quality factor (Q) of the lossless laser cavity and show that the time-bandwidth product (product of photon lifetime and maximum resonance frequency) is equal to on...

A semiconductor laser under negative optoelectronic feedback is applied to the generation of a microwave frequency comb through the nonlinear dynamics. The laser system is operated in a harmonic frequency-locked pulsing state, where its power spectrum is a microwave frequency comb that consists of multiples of a locking frequency. Every frequency component of the comb can be simultaneously stab...

The ability to generate phase-stabilized trains of ultrafast laser pulses by mode-locking underpins photonics research in fields, such as precision metrology and spectroscopy. However, the complexity of conventional mode-locked laser systems has hindered their realization at the nanoscale. Here we demonstrate that GaAs-AlGaAs nanowire lasers are capable of emitting pairs of phase-locked picosec...
