We further identified wavelength channels that influenced the prediction model.
To redshift further the wavelength to 1432 nm, a reduction of the growth temperature of the In0.11Ga0.89As1-ySby layer from 500 °C to 440 °C was necessary.
For further research, wavelengths at which moisture plays a role could be excluded during development of the model.
A recent study, on the other hand, shows that the existing evidence for a separate ultra-long GRB population with a new type of progenitor is inconclusive, and further multi-wavelength observations are needed to draw a firmer conclusion.
From the above, we can argue that the benefits of FE are especially valuable for relatively small arrays, with size say up to a few wavelengths, when adding a further (albeit virtual) wavelength to the array size produces a significant directivity upgrade.
Further, the resonant wavelength tuning possibilities of ADF are theoretically studied to cover the lower channels of CWDM systems.
Further, the emission wavelength of the distributed feedback laser is continuously tunable according to the temperature dependence of the refractive index.
With wavelength further decreasing, the contribution to the ratio from 1hh-1e transition became more and more weak, while the contribution from 1lh-1e became dominant.
Then considering the relation between beat length and temperature or operating wavelength, further discussions are made about its thermal stability and achromatic performance, and temperature ranges and the achromatic bandwidth are given for the qualified fiber wave plate.
Further, in the wavelength range [1510 nm, 1565 nm], the transmission imbalance between the output fields is below 0.85 dB for TE- or TM-polarized input light, respectively, while the phase errors in both cases are less than 4°.
