Tailored surface birefringence by femtosecond laser assisted wet etching.
Surface texturing is demonstrated by the combination of wet etching and ultrafast laser nanostructuring of silica glass. Using potassium hydroxide (KOH) at room temperature as an etchant of laser modified glass, we show the polarization dependent linear increase in retardance reaching a threefold value within 25 hours. The dispersion control of birefringence by the etching procedure led to achr...
متن کاملFabrication and Optical Characterization of Silicon Nanostructure Arrays by Laser Interference Lithography and Metal-Assisted Chemical Etching
In this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. In order to define silicon nanostructures, Metal-assisted chemical etching (MaCE) was carried out with silver catalyst. Provided solution (or materiel) in combination with laser interference lithogr...
متن کاملSurfactant-Assisted Etching of Nanochannels
The fabrication and functionalization of synthetic nanochannels has in the last years become of increasing interest for basic research as well as for applications. Nanochannels have an especially high surface-to-volume ratio which makes them ideal for handling very small amounts of liquid in nanofluidic devices or for designing highly sensitive sensing elements. In contrast to their biological ...
متن کاملDry-etching and characterization of mirrors on III-nitride laser diodes from chemically assisted ion beam etching
Vertical mirrors have been fabricated with chemically assisted ion beam etching (CAIBE) on OMVPE grown InGaN/AlGaN laser diode structures. AFM measurements show that smooth vertical sidewalls are obtained which exhibit a root mean squared (rms) roughness of only 40—60 A _ . The inclination angle of the etched mirrors is within $2° of vertical, as SEM studies indicate. Photopumping measurements ...
متن کاملER:YAG Laser Etching of Enamel
This in vitro study compares the etching effects of acid treatment and Er:YAG laser radiation on the enamel of extracted permanent human molars. Oval cavities in the buccal surface were prepared in the conventional manner and then the edges of the cavities were irradiated by Er:YAG radiation. Laser energy was 105 mJ and 208 mJ and the repetition rate was 1 Hz. The radiation was focused by a CaF...
