The study of excitation spectra (between 200 and 360 nm) was performed manually, adjusting the excitation wavelength every 5 nm and maintaining the emission wavelength at 450 nm.
To further reduce the cavity size while maintaining the resonant wavelength, we performed systematic FDTD simulations to obtain the cutoff frequencies of high-index dielectric-silver waveguide modes for various structural parameters (Figure 5).
In the alternative setup, the three single-wavelength lasers were coupled to the TIRF module via a polarization-maintaining wavelength multiplexer (Oz Optics, Ottawa, Canada).
In order to boost the long-wavelength response, while maintaining a strong short-wavelength response, we subjected the front side of the InP wafers to a H2 plasma (pressure of ∼85 mTorr, power density of 0.5 W/cm, and bias voltage of −450 V) before TiO2 deposition.
At the same time, photonic multilayers can be devised to present a Bragg peak that matches the absorption band of the dye but has no effect on longer wavelengths, maintaining a great deal of the transparency of the cell.
By varying the wavelength while maintaining the periodicity of the unit cell, stresses, SEDs and displacements are obtained and compared.
We achieved ~ 40% transparency across the visible wavelength while maintaining electrical conductivity by employing a TiN/Ti interlayer on quartz as a translucent conducting layer.
In the synchronous fluorescence technique, both excitation and emission monochromators are scanned simultaneously, with a constant wavelength interval maintained between excitation and emission wavelengths.
The fiber with this structure has the effective-core-area (Aeff) of more than 100 μm2 and dispersion slope of less than 0.065 ps/nm2/km at 1.55 μm wavelength simultaneously while maintaining the good bending loss.
Wavelength-swept lasers can provide high axial scan / sweep rates while maintaining both narrow linewidth and broad wavelength tuning range and are a key technology for ultrahigh speed swept source OCT [ 25– 325.
In wavelength-routed DWDM (Dense Wavelength Division Multiplexing) networks, more and more DPEs (Dynamic Power Equalizers) are being implemented in optical crossconnects or add-drop multiplexers for the purpose of maintaining uniform power on working wavelengths.
