We demonstrate a technique to fabricate spherical micromirrors with a programmable focal length by microfluidic capillary. Micromirrors with focal lengths of 13 μm, 19 μm, 28 μm, 50 μm, and a flat mirror were fabricated and characterized. These micromirrors show a great ability to converge light into a focal point. This technique also introduces the concept of fabricating and integrating optical components with microfluidic channels. © 2003 American Institute of Physics.

    For microfocusing x-ray mirrors, an elliptical shape is essential for aberration-free optics. However, it is difficult to polish elliptical mirrors to x-ray-quality smoothness. Profile coatings have been applied on both cylindrical and flat Si substrates to make the desired elliptical shape. In...

    The temporal Talbot effect and soliton propagation in an optical fiber were exploited to yield a series of pulse train sources with tunable repetition rate simply through variation of the pulse train power in sections of the fiber. In a dual-repetition-rate configuration, 10 and 20 GHz or 10 and...
