Complete and accurate records of vaccine temperature history are vital to preserving drug potency patient safety. However, previously published storage handling guidelines have failed indicate a need for continuous monitoring in refrigerators. We evaluated the performance seven digital data logger models as candidates refrigerated vaccines, based on following criteria: out-of-box compliance with manufacturer accuracy specifications over range use; measurement stability extended, proper setup...
Accidental freezing of refrigerated vaccine represents a significant public and private healthcare cost. Freeze-damaged vaccines lose their effectiveness, putting health at risk. U.S. immuni...
Vaccine temperature control failures represent a significant public and private healthcare cost. Vaccines damaged by excessive heat or freezing lose their effectiveness, putting health at risk. Some vaccine administration programs recommend placing water bottles inside domestic refrigerators used for storage as thermal ballast, to mitigate excursion risks. However, the effect of variable ballast loading on refrigerator performance has not been thoroughly quantified documented, generalized...
Kerr-induced synchronization (KIS) [1] involves the capture of a dissipative Kerr soliton (DKS) microcomb [2] tooth by reference laser injected into DKS resonator. This phase-locking behavior is described an Adler equation whose analogous form describes numerous other physical systems [3], such as Josephson junctions [4]. We present AC version KIS similar to microwave-driven junctions, where periodic occurs so-called Shapiro steps. demonstrate consistent results in AC-KIS dynamics predicted...
We present a terahertz-carrier frequency comb based on Kerr-Induced Synchronization (KIS) of an Optical Frequency Comb (OFC), wherein commercially available C-band laser harnesses OFC tooth and captures the repetition rate (frep) OFC. The linear relationship between modulation frep enables direct transfer to frep. In addition, large KIS effect bandwidth facilitates tuning over wide range frequencies. This work addresses THz gap by providing path for millimeter wave generation, utilizing...
We demonstrate that a dissipative Kerr soliton comb tooth can be captured by another injected pump laser, resulting in induced synchronization. This regime is highly significant for metrology applications, where the passively lock onto reference clock laser. The dynamics of system also enable other forms locking, at fixed offset from entering syntonization regime. Similar to breather entrainment, we establish frequency correlates with soliton's repetition rate.
We show that in the Kerr-Induced Synchronization (KIS) regime, an external reference pump laser allows for control of opposite (in frequency) Dispersive Wave (DW) power and frequency, through self-balancing cavity soliton. report increase more than 20~dB DW octave-spanning comb at 780 nm, with a telecom C-band, while tuning over three teeth. Our work paves way significant improvement carrier-envelope offset frequency detection combs.
The generation of controlled and arbitrarily tunable terahertz radiation, essential for many applications, has proven challenging due to the complexity experimental setups fabrication techniques. We introduce a new strategy involving control over repetition rate integrated frequency comb, using Kerr-induced synchronization, that results in terahertz-voltage-controlled oscillator. By modulating reference laser, we can transfer any microwave waveform onto microcomb via linear function based on...

Kerr-induced synchronization enables direct control of a soliton microcomb’s repetition rate by reference laser’s frequency. We demonstrate that dynamically tuning this frequency creates coherent RF-to-THz optical link, resulting in voltage-controlled THz oscillator.
Dissipative Kerr solitons (DKSs) intrinsically exhibit two degrees of freedom through their group and phase rotation velocity. Periodic extraction the DKS into a waveguide produces pulse train yields resulting optical frequency comb's repetition rate carrier-envelope offset, respectively. Here, we demonstrate that it is possible to create system with single but different velocities by employing dual driving forces. By recasting these frequencies, demonstrate, experimentally theoretically,...
The phase-coherent frequency division of a stabilized optical reference laser to the microwave domain is made possible by combs (OFCs). Fundamentally, OFC-based clockworks rely on ability lock one comb tooth this laser, which probes stable atomic transition. active feedback process associated with locking introduces complexity, bandwidth, and power requirements that, in context chip-scale technologies, complicate push fully integrate OFC photonics electronics for fieldable clock...
