The net modal gain coefficient (G) was also characterized via VSL measurement10,29, which we performed at different pump fluences much higher than optical the gain threshold (thus in multi-excitonic regime), by using the integrated intensity of the recorded PL spectra as a function of the str...
Continuous-wave lasing at room temperature is critical for integration with opto-electronic devices and optimal modulation of optical interactions4,5. Plasmonic nanocavities integrated with gain can generate coherent light at subwavelength scales6,7,8,9, beyond the diffraction limit that constrains mode ...
In these experiments we measured [Ca2+] in the oviDN soma. Somatic [Ca2+] is often thought of as a proxy for a cell’s spike rate19. To gain insight into the relationship between membrane potential (Vm), spike rate and [Ca2+] in oviDNs, we activated CsChrimson while performing eith...
the modal reflectivity of the facet can be enhanced to 97.6% by introducing a metallic hole that has a diameter of 990 nm. This means that the optical mirror loss is decreased by more than 40%. The ratio between the transmittance and the energy that is not reflected back (T/(1 ...
The SBS threshold is inversely proportional to the product of the SBS gain factor and the linewidth Γ, so the SBS gain factor and the linewidth should be as large as possible. We have designed waveguides with robust optical properties and large acousto-optic effective areas. Measurements of a...
Modal gains of these modes are compared to the calculated threshold gains for each mode. Because of non-uniform gain saturation by the operated mode, modal gains for higher-order modes increase with drive current due to beneficial overlap of their fields with the gain. When one of the higher...
The threshold modal gain and excitation power are found to depend inversely on the microtube diameter.Junseok HeoBhowmick, S.Bhattacharya, P.IEEE Transactions on Quantum Electronics.J. Heo, S.

the resonant cavity mode of this structure is tuned to a slightly shorter wavelength (λcav≈971 nm) than the InGaAs QW at (λQw≈980 nm). Therefore, a minimum CW threshold current of 166 μA is achieved for the 8 μm device at 240K, where the gain peak overlaps the cavity mode,...
