Investigations of the goldblack structure have revealed the importance of coating uniformity in achieving high absorption at longer wavelengths.
Thin passivation layer suffers from high absorption at the metal interface while thick passivation layer suffers from poor heat dissipation in the ridge waveguide and high scattering loss, resulting in high threshold.
Substrate side irradiation is widely used for a thin film removal process because high absorption at the film/substrate or film/film interface leads to complete isolation of thin film by single shot irradiation of laser pulse with low energy.
We have found that the absence of alkyl substitutions on the thiophene units increases the planarity of the polymer backbone leading to a thin film with a higher absorption at low wavelengths and larger hole mobility compared to an analogous copolymer.
In contrast, an interference filter has low absorption at the excitation wavelength and high absorption at the emission wavelength.
The stacking of high absorption at different frequencies creates a broadband absorption under the action of all layers of graphene.
As both polymers show a high absorption at 1150 1000 cm−1, the intensity of this band did not decrease.
By utilizing limestone's high absorption at 11.2 μm they were able to identify areas of deterioration.
Efficiency in erbium emissions can be improved by co-doping with ytterbium, thus assuring a high absorption at 980 nm, where high-power diode lasers are commercially available.
Recently, monolayer MoS2 shows great potential for generating various optoelectronic devices [25 34] and for photocatalytic applications owing to high absorption at the short wavelength side [35, 36].
