Sentence examples for photon lifetime from inspiring English sources

Photon lifetime in resonator.

The total switching time is expected to be restricted by the photon lifetime in cavity due to the ultrafast response speed of polymer.

According to these investigations, K-factor [8, 11] has been recognized to be one of the limiting factors for the modulation bandwidth of QD lasers, which accounts for the effect of photon lifetime, differential gain, and nonlinear gain compression factor.

We combine the plasmonic properties of metallic nanoparticles enabling a label-free bioanalytical approach with the cavity ring-down method (CRD) in a miniaturized fluidic device as a sensitive and fast optical photon lifetime measurement.

A proper assessment of the performance of micro-cavities depends on two crucial parameters - which are the resonance quality factor, Q, and the modal volume, V [13] - where the Q-factor value directly determines the photon lifetime within the cavity and the modal volume, V, is the key factor for assessing the impact of the electromagnetic confinement of the mode within the cavity.

It is advantageous to use an optical cavity, such as a whispering gallery mode (WGM) resonator [21] (see Figure 1b), to provide this field, as the light in the optical cavity is able to sample the mechanics many times due to its long photon lifetime and leads to resonantly enhanced optomechanical coupling.

Here, we demonstrate a two-photon lifetime microscopy technique that utilizes this new oxygen sensor for examining the vascular networking impact on intravascular oxygen tension.

Practically, photothrombosis and wide-field LSCI can be simple additions to existing two-photon lifetime microscopy systems using an available camera port and the ability to swap excitation and detection filters for the respective lasers.

Our home-built two-photon lifetime fluorescence microscope uses a femtosecond Ti-Sapphire laser to excite the sample and a time-correlated single-photon counting card to record the lifetime of the emitted fluorescence, providing extra intensity-independent imaging contrast.

The fit, mainly performed on bi- and tri-exponential fluorescence decay models at variable number of photons, lifetimes and amplitudes, were always convergent to the true set of parameters.

The impact of reductions in intravascular oxygen tension on the metabolic health of the surrounding tissue may be obtained from two photon autofluorescence lifetime microscopy of NADH [ 43, 44] as well as imaging of neuronal structural dynamics [ 45].
