In this paper we describe how circular silica micro disk resonators can be coupled to erbium doped fiber to create a desired emission spectrum. This approach could lead to very compact and inexpensive multiple wavelength lasers. We demonstrate here a selective erbium emission at a single wavelength using a silica microcavity.

Liquid crystal on silicon (LCoS)-based spatial light modulators (SLMs) are versatile adaptive optical elements. In microscopy, among their applications are aberration sensing and correction in wide-field microscopy and also the implementation of holographic optical tweezers. For aberration correction, the required scene-based wavefront sensing can be implemented as a modified correlation-based Shack-Hartmann approach where a high-resolution SLM first senses and then corrects the aberrations. For the implementation of holographic optical tweezers, the SLM serves as a variable optical beam-splitter which is addressed with holograms computed by fast algorithms implemented on the graphics processing unit (GPU) of a common PC almost in real-time.

Two types of planar centering mechanism with shape edge were fabricated and demonstrated their performance in this paper, which effectively reduce the tilt angle of dielectrically liquid lens to 0.2deg.
